To calculate the current in the circuit when key is closed
Explanation:
Electric circuit
An electrical circuit is a closed path in which electrons from the source of current flows that is battery or cell.
It consist of : Wire , battery , Key or switch ,Ammeter, voltmeter ,resistance .
For current to flow , the battery must be connected and key or switch should be closed and there should not be any broken part in circuit .
We can calculate the magnitude of current in the circuit by applying ohm's law that is :
V=IR
where V=potential difference
I=current
R= resistance of wire
