Question

Five equal resistances each of resistance R are connected as shown in the figure. A battery of V volts is connected between A and B. The current flowing in the circuit is

• A. $\frac{2V}{R}$
• B. $\frac{3V}{R}$
• C. $\frac{V}{R}$
• D. $\frac{V}{2R}$

Answer 1

The correct option is D $\frac{V}{2R}$

A balanced Wheatstone's bridge exists between A & B.
$R_{eq}=R$
current through circuit is $\frac{V}{R}$
current through AFCEB$=\frac{V}{2R}$
