Question

what happens to the current in a circuit if its resistance is doubled

Answer 1

if resistance is doubled then the current would be halved as resistance is inversely proportional to the current flowing in a circuit. that is if the resistance is doubled the current would be halved.

Answer 2

In a circuit, if the resistance is doubled, the current becomes half.

• The current and resistance have an indirect relationship and one increases as the other tends to decrease, vice versa.
• Any increase in resistance affects the flow of current by disrupting it and the materials, whose resistance is high, are known as insulators.
• The inverse relationship between current, I and resistance,R can be shown using I=V/R, where V is the voltage.
