A) \[{{L}_{1}}={{L}_{2}}={{L}_{3}}\]
B) \[{{L}_{1}}={{L}_{2}};{{L}_{3}}=0\]
C) \[{{L}_{1}}={{L}^{3}};{{L}^{2}}=0~\]
D) \[{{L}_{1}}>{{L}_{2}}>{{L}_{3}}\]
Correct Answer: C
Solution :
As inductance \[{{L}_{2}}\] was wound using the similar wire but the direction of winding is reversed, so flux through \[{{L}_{2}}\] is zero. \[\therefore \] \[{{L}_{2}}\propto \,\phi =0\] Also, \[{{L}_{1}}={{L}_{3}}\] Therefore, \[{{L}_{1}}={{L}_{3}},\,{{L}_{2}}=0\]You need to login to perform this action.
