Question

Can current flow in the circuit if there is no potential difference applied?

Answer 1

Answer:

MARK ME AS BRAINLIEST ❤️

Explanation:

Ideally yes, it can flow. Consider a circuit where components are connected using ideal conductors. Any voltage drops appear only across components— this is how we do all our calculations. Conductors carry the current between components, and no voltage drop occurs in the conductors.

Answer 2

Explanation:

Ideally yes, it can flow. Consider a circuit where components are connected using ideal conductors. ... This resistance is the reason for wires and cables to get heated in actual wiring and circuits. Superconducting materials have zero resistance and are able to carry huge currents without any voltage drop.
