In the given circuit, the current in resistance R 3 is:

Options

  1. A1 A
  2. B1 . 5 A
  3. C2 A
  4. D2 . 5 A

Correct answer

A. 1 A

Step-by-step solution

Equivalent resistance, R eq = 2 Ω + 4 × 4 4 + 4 Ω + 1 Ω = 5 Ω Current through battery, i = V R e q = 10 5 = 2 A Current in resistance R 3 = 2 × 4 4 + 4 = 2 × 4 8 = 1 A
