Question

A circuit is made from two resistors in series and a battery. As more resistors are added in series, how is the current coming out of the battery affected?

• A. Increases
• B. Remains the same
• C. Decreases
• D. Not enough information to determine

Answer 1

Answer: (C)

Decreases

From ohms law, current in the circuit $I=\frac{V}{R_{eq}}$ $⟹I\propto \frac{1}{R_{eq}}$

Equivalent resistance of the circuit increases by adding more resistances in series.

Thus current flowing in the circuit decreases.
