Question

The equivalent resistance between AB in the circuit is

• A. $\frac{5R}{4}$
• B. $R$
• C. $\frac{5R}{7}$
• D. $\frac{5R}{3}$

Answer 1

The correct option is A $\frac{5R}{4}$

Points C, D and E are at same potential. So the circuit can be
redrawn as

Equivalent resistance, $R_{eq}=\frac{5R}{4}$
