Current Electricity Ques 14
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 through the path $A F C E B$ 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: 14.(d)
Solution:
A balanced Wheatstone’s bridge exists between $A$ & $B$.
$\therefore R _{\text{eq }}=R$
Current through circuit $=V / R$
Current through $I=V / 2 R$
