Question

Which of the following statement is correct ? A . potential difference is measured by ammeter . B . The unit of potential difference is ampere C . Battery is a source of potential difference in a circuit D . potential difference cause charges to remain stationary​

Answer 1

Answer:

C.Battery is a source of potential difference in a circuit.

Explanation:

A battery is a source of electrons and positive ions which sets one of it's terminal (cathode) at negative potential and the other (anode) at positive potential. Hence a battery is a source of electricity(electrons) which sets a potential difference across the battery terminals.
