Question

25. a) Find the equivalent resistance across the two ends A and B of the following circuit:
Assume that P and Q are at the same potential.
R2
Ro
RR
22-2
Rom​

Answer 1

R/2

its easy..........

Answer 2

Answer:

r/2

Explanation:

in the circuit the current will not flow through PQ. resistance so the upper equivalent resistance is 1r and r paralle

so r/2 is the answer
