In the given circuit, The current through battery is

Options

  1. A0 . 5   A
  2. B1   A
  3. C1 . 5   A
  4. D2 . 5   A

Correct answer

C. 1 . 5   A

Step-by-step solution

In the given circuit, diode D 1 is reverse biased, so it will not conduct but D 2 , D 3 are forward biased, so they will conduct, hence corresponding equivalent circuit. For the given circuit is Now, the equivalent resistance of the circuit is R eq = 515 × 20 5 + 5 + 20 + 20 3   Ω Current through battery, I = 10   V 20 3   Ω = 1 . 5   A
