Time Response of Reactive Circuits - Engineering
Q1: With an RL integrator, at the instant of the rising pulse edge,A all the input voltage is across the resistor
B all the input voltage is across the inductor
C 63 percent of the input voltage is across the resistor
D 63 percent of the input voltage is across the inductor
ANS:B - all the input voltage is across the inductor Because just before the instant of rising pulse voltage capacitor was acting as a short ckt, and according to inductor property it will not allow sudden changes hence just after or at the instant of rising pulse voltage it remains in open circuit hence all the input voltage appears across the open circuit or across the inductor. |
