Question

Which relation defines mutual inductance using the flux linkage \[N_2\phi_{21}\] and current \[I_1\] ?

विकल्प

• \[M=\frac{N_2I_1}{\phi_{21}}\]

• \[M=\frac{N_2\phi_{21}}{I_1}\]

• \[M=N_2\phi_{21}I_1\]

• \[M=\frac{I_1}{N_2\phi_{21}}\]

Answer 1

The total flux linkage in the secondary coil is proportional to the primary current: \[N_2\phi_{21}=MI_1\] . Dividing by \[I_1\] gives \[M=\frac{N_2\phi_{21}}{I_1}\] .
