A) 6.25 H
B) 12.5H
C) 25 H
D) 50 H
Correct Answer: C
Solution :
Mutual inductance of transformer \[M\propto {{N}_{1}}{{N}_{2}}\] \[\frac{{{M}_{1}}}{{{M}_{2}}}=\frac{{{N}_{1}}{{N}_{2}}}{N{{}_{1}}N{{}_{2}}}\] \[\frac{25}{{{M}_{2}}}=\frac{5\times 10}{10\times 5}\] \[\therefore \] \[{{M}_{2}}=25\,henry\]You need to login to perform this action.
