# Consider RL-circuit R wwww ups. E 1. Determine the differential equation governing the current I (in amperes) on the circuit. av 2. Solve the equation to find the current in the case of constant electromotive force E(t) = E, constant. Evaluate the constant of integration by using the condition I(0) Io. = 3. Determine the limit lim I(t) where I (t) is obtained form the above question. 1-00 4. Let R = 100 ohms, L = 2.5 henries, E(t) = 110 cos 314t. Find the steady-state solution. eeee
