A resistor is connected to a battery of 12 V emf and internal resistance 2 . If the current in the circuit is 0.6 A, the terminal voltage of the battery is :

Options

  1. A10 V
  2. B1.2 V
  3. C12 V
  4. D10.8 V

Correct answer

D. 10.8 V

Step-by-step solution

The terminal voltage V of a battery discharging in a circuit is given by the relation: V = E - Ir Substituting the given values E = 12 V, r = 2 , and I = 0.6 A: V = 12 - (0.6 2) V = 12 - 1.2 V = 10.8 V Answer: 10.8 V
