Question

difference between emf and potential difference??​

Answer 1

Measurement of: The key difference between voltmeter and ammeter is that both these devices measure different quantities. One measure voltage and the other measure current. A voltmeter measure voltage difference between two points in the circuit while ammeter measure current in the circuit.

YOUR'S ANSWER......

............................... The emf is the the potential difference between the terminals of a battery when no current is flowing through an external circuit when the circuit is open. Potential difference is the voltage across the terminals of the battery when the current is being drawn from it to an external.............
