Current Electricity - Result Question 105

110. 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 $A F C E B$ will be

[2004]

(a) $\frac{2 V}{R}$

(b) $\frac{3 V}{R}$

(c) $\frac{V}{R}$

(d) $\frac{V}{2 R}$

Show Answer

Answer:

Correct Answer: 110. (d)

Solution:

  1. (d) A balanced Wheststone’s bridge exists between $A & B$.

$\therefore R _{\text{eq }}=R$

Current through circuit $=V / R$

Current through $AFCEB=V / 2 R$
