41. The current in the following circuit is
[1997]
(a) $1 A$
(b) $\frac{2}{3} A$
(c) $\frac{2}{9} A$
(d) $\frac{1}{8} A$
Show Answer
Answer:
Correct Answer: 41.(a)
Solution:
- (a) Resistance of $A C B, R^{\prime}=3 \Omega+3 \Omega=6 \Omega$.
For net resistance between $A$ and $B ; R^{\prime}=6 \Omega$ and $3 \Omega$ are in parallel.
$ R _{A B}=\frac{3 \times 6}{3+6}=\frac{18}{9}=2 \Omega $
Current in circuit $(I)=\frac{E}{R _{A B}}=\frac{2}{2}=1 A$
