| If the total resistance in a series circuit doubles, current will:

A. be the same

B. be doubled

C. reduce source voltage

D. be halved

Please scroll down to see the correct answer and solution guide.

Right Answer is: D

SOLUTION

When the resistances are connected in series, the equivalent resistance will be the sum of all the resistances. In series circuit, the current flows through circuit is same.

We know that V = IR

For constant voltage, resistance is inversely proportional to current.

If the total resistance in series circuit doubles, the current will become half.
