ON CAPAC Transient RL Circuit Consider the circuit shown in the figure. The resistance of the wire used to make the inductor is negligible compared to the resistors in the circuit. V-140 V, R; -10.Ohms, Ry - 1100 Ohms, and L-200 H RI WWW For this part, assume that switch S has been closed for a long time so that steady currents exist in the circuit. Find (1) the battery current, (2) the current in resistor Ry, and (3) the...
4. The current in an RL circuit increases to 95% of its final value 3 seconds after the switch is closed. The inductance in the circuit is 0.310 H. Find the inductive time constant and resistance for the circuit. (Assume the inductor has neglible resistance). Show your work. 5. At resonance, the reactance of the inductor (L) and the capacitor (C) cancel each other so that the impedance (Z) is just the resistance (R). Using the values from this experiment...
The Natural Response of an RL Circuit In summary, to find the time constant of an RL circuit, find the Thevenin equivalent resistance se Learning Goal: To analyze an RL circuit 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 other circuit quantities, such as current, voltage, power, or energy. The natural response of an RL...
