A) \[0.2\text{ }A\]
B) \[0.3\text{ }A\]
C) \[0.4\text{ }A\]
D) \[0.6\text{ }A\]
Correct Answer: C
Solution :
: From figure, Voltage across all the three branches is the same. \[\therefore \] \[10{{I}_{1}}=15{{I}_{2}}=30{{I}_{3}}\] or \[{{I}_{1}}=1.5{{I}_{2}}\] ?....(i) \[15{{I}_{2}}=30{{I}_{3}}\] or \[{{I}_{3}}=\frac{1}{2}{{I}_{2}}\] ???..(ii) Also \[I={{I}_{1}}+{{I}_{2}}+{{I}_{3}}\] \[1.2=1.5{{I}_{2}}+{{I}_{2}}+\frac{1}{2}{{I}_{2}}\](Using (i) and (ii)) \[=\frac{3{{I}_{2}}+2{{I}_{2}}+{{I}_{2}}}{2}\]You need to login to perform this action.
