A variable resistor is set to a value of 5 ohms, and a current-voltage (I-V) graph (with I on the y-axis and V on the x-axis) is plotted for it. Its resistance is then doubled to 10 ohms. What effect will this have on its I-V graph?​

When the resistance is doubled, the current reduces by half.

Ohms law

Ohms law states that the voltage applied to a circuit is directly proportional to the current flowing in the circuit.

V = IR

V/R = I

where;

  • V is emf of the battery
  • R is resistance
  • I is the current

From the equation above, when the resistance is doubled, the current reduces by half.
