For the circuit shown in the figure, the current I will be

Options

  1. A0 . 75   A
  2. B1   A
  3. C1 . 5   A
  4. D0 . 5   A

Correct answer

B. 1   A

Step-by-step solution

In the above circuit the cells are connected with opposite polarity it means the net EMF is, E = E 1 + E 2 = 2 + 4   V = 6   V and, all the resistance is connected in series, R = R 1 + R 2 + R 3 ⇒ I = 2 + 4 4 + 1 + 1 = 6 6 = 1   A .
