Question

Part A Learning Goal: F the gen cituit Figu e 1 mH aas me he maktbef ek switch has been up fo a long time and moves do att 0. Find the ini al cure t through the inductor. Assume that 1-100.0 mA. R.-24.0 kS·R3-80.0 ks. and L-23.0 To aralyze an RL cirouit to determine the initial current through an inductor, the time constant, and the expression for the natural response of the inductor current, and to use the expression for the inductor current to find ather circuit quantibies,such as current votage, powwer, or energy Express your answer to three signiticant figures and include the appropriate units View Available Hints) The natural response of an RL circuit is the response of the inductor currert to the sudden removal of a DC source. When this ocours, the inductor neleases he stored energy i(0 )=i(09-_ Value Units Submit Part B-Find tha tima constant, r, atar The disgram (Figure 2 shows the circuit the instant aftert-0. Find the time constent, T.Assume thst I-100.0 mA R-240k, R-08.0 kn,andL 23.0 mH Express your answer to three signticant figures and include the appropriate units View Available Hines) Value Units Submt Part C-For the original circuit, tnd an expression for the inductor current ㈹, for 0 ▼ Enter an expression for he inductor ourent, i(t).for Express your answer as an algebraic expression in terms of I.R. R.and Viaw Available Hints) i(t) Submt Figure 1of2 Part D-For the original circuit, find an expression for the resistor voltage, vt. for t O+ ▼ What is the cprassion for the voltage rt) in V acrossrosistor R for t0 Choose the correct answe.
