If voltage doubles from 60 V to 120 V with the same resistance, current will

Explanation:
When resistance stays the same, current changes in proportion to voltage according to Ohm’s law: I = V / R. If you increase the voltage from 60 V to 120 V while keeping R constant, the current becomes I = 120 / R, which is twice the original current (since 120/R = 2 × (60/R)). So the current doubles. This also means power rises as well, since P = V × I; with both V and I doubling, power becomes four times the original.

When resistance stays the same, current changes in proportion to voltage according to Ohm’s law: I = V / R. If you increase the voltage from 60 V to 120 V while keeping R constant, the current becomes I = 120 / R, which is twice the original current (since 120/R = 2 × (60/R)). So the current doubles.
