In the figure shown, what is the current (in Ampere) drawn from the battery? You are given: R 1 = 15 Ω , R 2 = 10 Ω , R 3 = 20 Ω , R 4 = 5 Ω , R 5 = 25 Ω , R 6 = 30 Ω , E = 15 V

Options

  1. A9 / 32
  2. B7 / 18
  3. C13 / 24
  4. D20 / 3

Correct answer

A. 9 / 32

Step-by-step solution

The equivalent resistance R e q of this given network is, R e q = 15 + 25 3 + 30 = 45 + 25 + 90 3 = 160 3 By applying ohm's law, the Current i through the battery is i = 15 160 3 = 15 × 3 160 ∴ i = 9 32   A
