Question

if the current through a resistor becomes double then the power becomes​

Answer 1

Answer:

Double

Explanation:becomes power depends on current..

Answer 2

Answer:

power becomes four times.

Explanation:

If current is I and voltage is V , then resistance R=VI and power is given by P=V⋅I . As such when both the current and voltage in a circuit are doubled, resistance becomes R=2V2I=VI and hence remains same. However, power becomes P=2V⋅2! −4V⋅
