    An electric current which vary for a small finite time, while growing from zero to maximum or decaying from maximum to zero, is called a transient current.
    Growth of current in an inductor at any instant of time t is given by
    I = I0(1 – e  -Rt / L)
    where, I0 = maximum current, L = self inductance of the inductor and R = resistance of the circuit.
    Here R / L = τ, is called time constant of a L – R circuit.
