Current Through a Circuit
A Current is the rate of flow of electrical charge. Current is measured with an ammeter.
Current Formula
Where; I is the current, Q is the charge and t is the time
The unit of electric current is Coulomb per second, and we give specific name Ampere (A).
1A=1C/s
Example: If the steady current 25 A flows in a wire for 5 minutes, find the charged passed in any point in the circuit.
You should have done the following Q = (2.5C/s) (300s) and come up with the answer of 750C

- A charge carrier is any charged particle capable of moving
- The space around an electric charge is called the electric field.
- Drift velocity is the average velocity that an electron attains due to an electric field.
