Chapter , Problem 28

(choose chapter or problem)

(II) You want to turn on the current through a coil of selfinductanceL in a controlled manner, so you place it in serieswith a resistor R = 2200 Cl, a switch, and a dc voltagesource Vq = 240 V. A fte r closing the switch, you find thatthe current through the coil builds up to its steady-statevalue with a time constant r. You are pleased with thecurrents steady-state value, but want r to be half as long.What new values should you use for R and V0?
