Two coils of self inductances 2 mH and 8 mH areplaced so close together that the effective fluxin one coil is completely linked with the other.The mutual inductance between these coils is(a) 6mH(c) 16mH(b) 4mH(d) 10mH |

Answer» (d) 10mH is the answer i guess the mutual inductance is given by √(L1*L2)here L1 = 2mH , and L2 = 8mH so, mutual inductance = √2*8 = √16 = 4mH. option B. |
