Question

Differentiate between potential difference and electromotive force

Answer 1

Potential difference is the voltage across terminal in a closed circuit
Electromotive force is the voltage across terminals in an open cicuit

Answer 2

Apotential diffrent is voltage across the cell or battery in Aclosed circuit while e.m.f is voltage across the cell or battery on an open circuit

Answer 3

_{Potential difference is the total voltage across the terminal of a bettery while electromotive force is the amount of current}
