Question

If two coils have self inductance L1 and L2 the coefficient of mutual induction will be: (A)  M propto √L1L2  (B)  M propto √( (L1/L2) )  (C)  M propto √( (L2/L1) )  (D) none of these

Tardigrade Admin · Accepted Answer

The coefficient of mutual induction is M propto √L1 L2

Q. If two coils have self inductance $L_{1}$ and $L_{2}$ the coefficient of mutual induction will be:

$M \propto L_{1} L_{2}$

$M \propto (\frac{L _{1}}{L _{2}})$

$M \propto (\frac{L _{2}}{L _{1}})$

none of these

The coefficient of mutual induction is $M \propto L_{1} L_{2}$

Q. If two coils have self inductance L1​ and L2​ the coefficient of mutual induction will be:

M∝L1​L2​​

M∝(L2​L1​​)​

M∝(L1​L2​​)​
