The current through the battery shown in the circuit is

Options

  1. A1 . 33     A
  2. B1 . 71     A
  3. C2 . 00 A
  4. D2 . 31     A

Correct answer

C. 2 . 00 A

Step-by-step solution

Since diode D 1 is reverse biased, therefore it will act like an open circuit. Effective resistance of the circuit is R = 4 + 2 = 6 Ω . Current in the circuit is I = E / R = 12 / 6 = 2 A.
