b) Given an RL circuit with the equation dI L- + RI = 900, dt where L is the inductance, R is the resistance and 900 is the voltage source. i. Show that the solution of the above equation is 900 + Ce R Rt I(t) = ii. The series are connected with inductance 350 henry, and the resistance is 18 ohms. Find I(t) if the initial current I(0) = 0. Calculate the current I(t) at time t = 1 minute. b) Given an RL circuit with the equation dI L- + RI = 900, dt where L is the inductance, R is the resistance and 900 is the voltage source. i.
