What will be the most suitable combination of three resistors A = 2 Ω , B = 4 Ω , C = 6 Ω so that 22 3 Ω is equivalent resistance of combination?

Options

  1. AParallel combination of A and C connected in series with B
  2. BParallel combination of A and B connected in series with C
  3. CSeries combination of A and C connected in parallel with B .
  4. DSeries combination of B and C connected in parallel with A .

Correct answer

B. Parallel combination of A and B connected in series with C

Step-by-step solution

If the 2   Ω resistance and the 4   Ω resistance are connected in parallel to each other, then R ' = 4 × 2 4 + 2 = 4 3   Ω . If the resistance of 6   Ω is now connected in series to the previous combination. R e q = 2 × 4 2 + 4 + 6 = 22 3   Ω
