Question

What happen in an electric circuit if the resistance is increased assume voltage remain same ?

• A. the current will decrease
• B. the voltage will decrease
• C. the current will increase
• D. the voltage will increase
• E. the current will not change

Answer 1

Answer: (A)

the current will decrease

Current in the circuit $I=\frac{V}{R}$ $⟹I\propto \frac{1}{R}$ $(\because V=constant)$

As the resistance is increased keeping the voltage constant, thus the current in the circuit will decrease.
