Question
Problem 3: AV= 98-V source is connected in series with an R = 1.4-k2 resistor and an L = 26-H inductor and the current is allowed to reach
naxımum. At time t = 0 a switch is thrown that disconnects the voltage source, but leaves the resistor and the inductor connected in their own circuit.
Randomized Variables
V = 98 V
R= 1.4 k&Omega
L = 26 H
Part (a) How much time, in milliseconds, is needed for the current in the circuit to drop to 8 % of its value at t = 0?
