Electromagnetic induction If current in a conductor increases then according to Lenz's law self-induced voltage will Aid the applied voltage Tend to decrease the amount of current Aid the increasing current Produce current opposite to the increasing current Aid the applied voltage Tend to decrease the amount of current Aid the increasing current Produce current opposite to the increasing current ANSWER DOWNLOAD EXAMIANS APP
Electromagnetic induction Two coils have self-inductances of 10 H and 2 H, the mutual inductance being zero. If the two coils are connected in series, the total inductance will be 10 H 9 H 12 H 6 H 10 H 9 H 12 H 6 H ANSWER DOWNLOAD EXAMIANS APP
Electromagnetic induction Higher the self-inductance of a coil, Greater the flux produced by it Lesser its weber-turns Lower the e.m.f. induced Longer the delay in establishing steady current through it Greater the flux produced by it Lesser its weber-turns Lower the e.m.f. induced Longer the delay in establishing steady current through it ANSWER DOWNLOAD EXAMIANS APP
