If the potential difference across a resistor is doubled:A. only the current is doubledB. only the current is halvedC. only the resistance is doubledD. only the resistance is halvedE. both the current and resistance are doubled

If in a circuit both the potential difference and resistance are doubled, then:(a) current is doubled. (b) current is halved. (c) current remains same. (d) current is four times.

If the resistance of a wire doubled and the potential difference stayed the same, what would happen to the current?it would doubleit would halveit would stay the same
