The current \[{{n}_{2}}=3\xrightarrow{{}}{{n}_{1}}=2\] drawn from the \[4p\] source will be
A)0.67 A
B)0.5A
C)0.17 A
D)0.33 A
Correct Answer:
B
Solution :
The equivalent circuit is shown in the figure \[\frac{5}{10}=\frac{10}{20}\] The Wheatstone bridge is balanced. The \[\therefore \] resistance in arm BC is ineffective. Resistance along \[MO=(KK)\sigma 2{{s}^{2}},\sigma 2{{s}^{2}},\sigma 2p_{z}^{2},\pi 2p_{x}^{2}\approx \pi 2p_{y}^{2},\] Resistance along \[\overset{*}{\mathop{\pi }}\,2p_{x}^{1}\approx \overset{*}{\mathop{\pi }}\,2p_{y}^{0}\] Effective resistance \[\because \] Current \[=\frac{1}{2}[{{n}_{b}}-{{n}_{a}}]\]
