5PRACTICE PROBLEM
A circuit consists of a resistor with resistance Ra and an inductor with inductance La connected in series to an ideal battery. Initially, the switch is open and no current flows through the circuit. At t=0, the circuit's switch abruptly closes. Determine the expression for the transient current as a function of time t in terms of Ra, La, and the steady-state current Is.
