1. Electric current - it is defined as the rate of flow of electric charges.I=Q/t.
SI unit of current is ampere (A).
2. I=Q/t
I=1C/1 second =1 ampere
3. Ammeter is used. it should always connected in series in a circuit.
4. Conventional direction of flow of electric current is positive to negative terminal whereas electrones flow from negative to positive terminal.
5. Q=10C, t=0.01 second, I =?
I=10/0.01 =1000 A
V=10 MV =10^6V
energy =V×Q
energy =10^6×10 =10^7 joule.
