Current
- A flow of electrons in any conductor is called current.
- It is represented by I and its unit is Ampere.
- An ammeter is used to measure the current by connecting in series with the circuit.
Ampere
- When 6.24 × 1018 electrons flow in one second across any cross-section of any conductor, the current in it is one ampere.
- (Or) If the potential difference across the two ends of a conductor is 1 volt and the resistance of the conductor is 1 ohm then the current through is 1 ampere.
