Two conducting coils are placed co - axially now a cell is connected in one coil then they will :

Two conducting coils are kept parallel to each other so that they have a common axis as shown in the figure. Now a bar magnet moves with velocity vecv towards coil (2) as shown in figure, then _____

Two coils C_(1) and C_(2) are kept coaxially as shown the coil C_(1) is connected to a battery and the coil C_(2) is connected to a galvanometer. The deflection in galvanometer can be increased by

Two inductor coils with inductances 10 mH and 20 mH are connected in series .What is the resultant inductance of the combination of the two coils?

A choke coil is connected to an AC source. Some power is dissipated in coil. Now a capacitor is connected in series with the coil and source is same, then average power dissipated in the circuit does not changes. If ratio of inductive reactance of coil and capacitive reactance of capacitor is 1/x then find x
