Question

A circuit is made from two resistors in parallel and a battery. As more resistors are added in parallel 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: (A)

Increases

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

Equivalent resistance of the circuit decreases by adding more resistances in parallel.

Thus current flowing in the circuit increases.
