Question

Two coils placed near to each other have number of turns equal to 600 and 300 respectively. On passing a current of 3.0 A through coil A, the flux linked with each turn of coil A is 1.2÷10000 Weber and the total flux linked with the coil B is 9.0÷100000 weber. Find self-inductance of A, the mutual inductance of the system formed by A and B.

Answer 1

Dear Student,

$$\begin{gathered} L_a=\frac{600*{\displaystyle \frac{1.2}{10000}}}{3}=0.024H \\ mutualinduc\tan ce=\frac{300*{\displaystyle \frac{9}{100000}}}{3}=0.009H \\ Regards \end{gathered}$$
