What happens to total current flow if the voltage of a series circuit is doubled while resistance remains constant?

When the voltage in a series circuit is doubled while the resistance stays constant, the total current flow also doubles. This relationship is described by Ohm’s Law, which states that current (I) equals voltage (V) divided by resistance (R), expressed mathematically as I = V/R.

In this scenario, if the original voltage is V and the resistance is R, the initial current would be I = V/R. When the voltage is doubled to 2V, the new current becomes I' = (2V)/R. Since we can see that I' = 2(V/R), it clearly indicates that the new current is twice the original current.

This principle is fundamental in electrical engineering and physics, demonstrating how current behaves in response to changes in voltage under constant resistance conditions. Hence, the correct answer is that the total current flow doubles when the voltage in a series circuit is increased while keeping the resistance the same.
