A resistor is connected to a battery of 1212 V emf and internal resistance 2 Ω2\ \Omega. If the current in the circuit is 0.60.6 A, the terminal voltage of the battery is :

Options

  1. A1010 V
  2. B1.21.2 V
  3. C1212 V
  4. D10.810.8 V

Correct answer

D. 10.810.8 V

Step-by-step solution

The terminal voltage VV of a battery discharging in a circuit is given by the relation:

V=E−IrV = E - Ir

Substituting the given values E=12E = 12 V, r=2 Ωr = 2\ \Omega, and I=0.6I = 0.6 A:

V=12−(0.6×2)V = 12 - (0.6 \times 2)

V=12−1.2V = 12 - 1.2

V=10.8V = 10.8 V

Answer: 10.810.8 V
