| 3. | Which is/ are incorrect ? | |
|
The electric current is a flow of electric charges, called electrons, in a conductor such as a metal wire.
|
||
|
Current is measured by an instrument called voltmeter.
|
||
|
It is the potential difference between the ends of the wire which makes the electric charge to flow in the wire.
