CC is a measure of engine displacement, which is a volume measurement. In electrical terms, CC stands for constant current. CC is usually associated with an LED or some other type of indicator. When using a power supply, the desired voltage and maximum current are set. When the load requires more current than the maximum set, the PSU becomes a current source, and the current is limited to what was initially set while voltage drops, which is CC.

What You'll Learn
CC stands for constant current
CC stands for "constant current" in electrical terms. CC is often associated with power supplies, where it is used alongside CV ("constant voltage"). When using a power supply, you typically set the desired voltage and the maximum current. When the load is connected, it may require more current than the maximum you set, in which case the PSU becomes a current source, and the current is limited to the set value while the voltage drops accordingly. This is an example of CC in action.
CC and CV are usually associated with an LED or some other type of indicator. For instance, if the "CV" LED is lit, it means that the PSU is working correctly with your load. Most types of loads require constant voltage to operate. On the other hand, the PSU has a physical limit on how much current it can supply.
In power supplies, CC and CV are important indicators that help users understand and adjust the settings to their desired preferences. By setting the voltage and maximum current, users can manage the power output and ensure that their devices or equipment function optimally.
It is important to note that CC and CV are not the only acronyms used in the field of electrical engineering. There are other abbreviations, such as "OVP" (over-voltage protection), that are also relevant to power supplies and the overall functioning of electrical systems. Understanding these acronyms and their meanings is crucial for professionals working in this field.

CC is an indicator on power supplies
CC and CV modes only work within the current and voltage limits of the power supply. The power supply can switch between CV and CC modes as the load resistance changes. For example, if CC is set to 1A and CV to 5V, the power supply will be in CC mode when the load is below 5Ω and CV mode when it goes above 5Ω.
Most types of load require constant voltage to operate, so if the "CV" LED is lit, it means the PSU is working fine with the load. The PSU has a physical limit on how much current it can supply. If the load attempts to draw more, the PSU decreases the output voltage to keep the current consumed at its maximum, not beyond it. This mode is CC mode, and the PSU behaves as a current source, changing its output voltage to keep its current constant. Some types of rechargeable batteries require a mixed-mode charge, where the charge starts at constant current and finishes at constant voltage. Li-ion batteries are a good example.
If the "CC" light is on, the current on the display (which always shows the actual current flowing through the circuit) is the same as the current limit set, and the voltage limit set is higher than the actual voltage displayed on the power supply.

CC is a measure of engine displacement
CC, or Cubic Centimetres, is a metric measurement of engine displacement. It is a measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. This is calculated by multiplying the distance travelled by the piston (the stroke length) by the circular area of the cylinder, and then by the number of cylinders in the whole engine. The resulting figure is the capacity of the engine.
Engine displacement is often used as an indicator of an engine's size and, by extension, the power it might be capable of producing. Bigger engines are able to produce more torque, which is the force the pistons exert to spin the crankshaft. However, there is no direct correlation between engine capacity and horsepower. For example, a turbocharged engine with a displacement of 6,162 cc developed nearly twice the power of the 409 engine, which has a displacement of 6,700 cc.
Engine displacement is commonly used in advertising and regulating motor vehicles. In some countries, it is also used to determine the vehicle size class and, therefore, the cost of road tax for the vehicle. For instance, in Japan, engine displacement is one of the factors used to determine vehicle tax. In some European countries, there is one charge for engines over 1.0 litre and another at the level of about 1.6 litres. In many other countries, road taxes are not based on engine displacement.
Engine capacity is displayed in several formats, including litres, cubic inches, and cc. The volume of a cylinder is calculated by measuring the diameter (the bore) and taking the swept volume of the cylinder (the length the piston will travel up and down in the cylinder, or the stroke). The bore multiplied by the stroke gives the cylinder volume, and this figure is then multiplied by the number of cylinders to give the capacity of the engine.

CC can be read as cubic capacity
CC, or Cubic Capacity, is an important factor in automobiles, particularly two-wheelers, where it refers to the volume of the chamber of the vehicle's engine. This chamber is where the mixture of air and fuel is combined for combustion. The size of the chamber, or its cubic capacity, is directly related to the power output of the engine. The bigger the chamber, the more air and fuel mixture can be compressed to generate power.
The CC value is derived from the volume of the cylinder, which is calculated using the bore (diameter of the cylinder) and stroke (distance the piston travels). The formula for calculating the cubic capacity of an engine is: CC = π/4 x bore^2 x stroke x number of cylinders. For example, a bike with a bore of 50 mm and a stroke of 70 mm in a single-cylinder engine would have a cubic capacity of approximately 137.4 cc.
The ideal CC range for a vehicle depends on its intended use. For city rides or short commutes, a bike with 100 cc to 150 cc is ideal as it offers fuel efficiency and a smoother ride. For highway cruising or adventure trips, a range of 200 cc to 400 cc is suitable as it provides a balance between speed and endurance. If you're looking for racing or extreme performance, bikes with 500 cc and above deliver exceptional power and acceleration but require skilled handling and higher maintenance.
Cubic capacity is also related to the vehicle's torque, horsepower, and energy production. The larger the cubic capacity, the higher the torque, horsepower, and energy output. This is because a bigger chamber can hold more fuel and air mixture, leading to increased combustion and, subsequently, higher energy output. Additionally, cubic capacity can be used to measure the total distance covered by a vehicle by considering the total amount of fuel consumed in cubic metres.

CC can refer to the size of an engine
In electrical terms, CC stands for "constant current". It is often seen alongside CV, which stands for "constant voltage". CC is associated with a LED or indicator of some kind. When using a power supply, the desired voltage and maximum current are set. When the load requires more current than the maximum set, the PSU becomes a current source, and the current is limited to what was initially set while the voltage drops.
Now, CC can also refer to the size of an engine. CC stands for cubic centimetres, which is the metric measurement of engine capacity. Engine capacity is a measurement of engine displacement. Engine displacement refers to the volume of air pumped through the engine in one complete cycle. When someone says they have a "two-litre" engine, this is the cylinder capacity or volume in each cylinder inside the motor. These figures are then added together and displayed as a round figure. For example, a four-cylinder engine with cylinders displacing 500cc of volume each has an approximate capacity of 2.0 litres. The volume of a cylinder is calculated by measuring the diameter (also called the bore) and taking the swept volume of the cylinder (the length the piston will travel up and down in the cylinder, also called the stroke). Bore multiplied by stroke gives you cylinder volume, and then you multiply that figure by the cylinder count to get the capacity of the engine. Engine capacity can be displayed in litres, the imperial measurement of cubic inches, or cc.
