Question

For a series circuit containing only a resistor and an inductor, Kirchhoff's second law can be expressed by the first-order differential equation L di/dt + Ri = E(t), where L is the inductance, R is the resistance, E(t) is the impressed voltage, and i(t) is the current. A 90-volt electromotive force is applied to an LR-series circuit in which the inductance is 0.3 henry and the resistance is 60 ohms. Consider that initially, the series circuit has no current. 1. Use the given information to write the IVP (DE and initial conditions). 2. Solve the IVP from part a) to find the current function at any time t. (Include the interval of definition) 3. The steady-state current of a series circuit is given by lim(t->inf) i(t). What is the steady-state current of the series circuit in this problem?
