Question

expalin terminal voltage of a cell. ​

Answer 1

Answer:

Terminal voltage is the potential difference across the terminals of a load when the circuit is switched on. E.m.f is the maximum potential difference that can be delivered by a cell or a generator when no current flows through it. Terminal voltage is measured by voltmeter whereas, E.m.f is measured by potentiometer.

Answer 2

Answer:

Terminal voltage is the voltage / potential difference across the terminals of a cell or battery. If the cell/battery is not connected to circuit then the terminal voltage/p.d is equal to the e.m.f of the cell or battery.
