    Hello sir,
    My que is that how we can relate& make a concept of Mutual induction &Self induction in two coils joined in series & parallel.Actually there was a que. :-:confused:
    Two wires are wound on a long plastic tube in same sense.Two end of different wires are joined together on one side of plastic tube &other side's wiress are connected with source of current 'I' . Show that induced EMF is -(L1+L2-2M12)(∂i/∂t),where L1&L2 ARE SELF INDUCTANCES &M is the mutual inductance.In this que how the signs of direction are considered ,how concept is applied pls. reply its solution as soon as possible.:)
