Question

What will be equivalent resistance between point a and c?

Answer 1

Answer:

Correct option (a) 30 Ω Explanation: Lower resistance on extreme left and upper resistance on extreme right are ineffective. The resistance R2 and R3 are in series combination. Therefore their equivalent resistance. R'= R2 + R3 =10+10 = 20 Ω. Similarly, the resistance R5 and R6 are in series combination. Therefore their equivalent resistance, R"= R5+ R6 = 10+10 = 20 Ω. Now the equivalent resistances R' and R" are in parallel combination. Therefore their equivalent resistance.
