Question

As the resistance increases, the number of electrons passing through the circuit is affected. What is the effect on the current in the circuit?

  1. Current increases
  2. Current decreases
  3. Current remains same
  4. Cannot say

hintHint:

Resistance is inversely proportional to the current.

The correct answer is: Current decreases


    Resistance is the opposition faced by the flow of electric current in a circuit.
    We know,
    R = V over I
    Consider the voltage of a circuit constant.
    alpha space 1 over I
    Thus, resistance is inversely proportional to the current.
    Hence, when the resistance of a circuit increases, the current flow will decrease.
