In the given circuit the cells have zero internal resistance. The currents (in amperes) passing through resistance R 1 and R 2 respectively, are:

Options

  1. A0 , 1
  2. B2 , 2
  3. C0.5 , 0
  4. D1 , 2

Correct answer

C. 0.5 , 0

Step-by-step solution

Assume V F as 0 a s     V E = V B ⇒ Current in R 2 is zero V A - V D = 10   V ⇒ I = 10 20 = 1 2   A from A to D
