Question

If the voltage doubles, what will happen to the current?

Answer 1

It also doubles.

Explanation:

By Ohm's Law, `V=IR`, where V is the voltage, I is the current, and R is the resistance.

We can solve for current and replace V with 2V to see the result.

`=>I=(2V)/R`

This is equivalent to `I=2(V/R)`.

Therefore, we can see that if the voltage doubles, the current also doubles for the same resistance.
