Consider the following statements regarding the network shown in the figure. (1) The equivalent resistance of the network between points A and B is independent of value of G . (2) The equivalent resistance of the network between points A and B is 4 3 R (3) The current through G is zero. Which of the above statements is/are true?

Options

  1. A(1) alone
  2. B(2) alone
  3. C(2) and (3)
  4. D(1), (2) and (3)

Correct answer

D. (1), (2) and (3)

Step-by-step solution

R_ eff = (P+Q)(R+S) (P+Q+R+S) R_ cff = 4 3 R
