The equivalent resistance of the given circuit between the terminals A and B is :

Options

  1. A0   Ω
  2. B9 2   Ω
  3. C3   Ω
  4. D1   Ω

Correct answer

D. 1   Ω

Step-by-step solution

In the question circuit the resistance of 5   Ω , is short-circuited, it means the new equivalent circuit will be, ⇒ R A B = 3 × 3 2 3 + 3 2 = 1   Ω .
