Current
- The current is the amount of charge passing a point in a circuit every second
(It is helpful to think of current as the charge per second)
- Charge, current and time are related by the following equation:
- Where:
- Q = charge (measured in coulombs, C)
- I = current (measured in amps, A)
- You can rearrange this equation with the help of the formula triangle:
