Question

If the voltage and resistance in a circuit both double, what happens to the current? use ohm’s law to explain your answer.

Answer 1

One form of Ohm's law says:

                           Current  =  (voltage) / (resistance)

The voltage and resistance are the numerator and denominator
of the same fraction.  So if both of them double, the value of the
fraction doesn't change.

Nothing happens to the current.  It doesn't change.
