How much voltage will be dropped across a 5-mH inductor if a motor changing state causes a 1 mA surge of current to flow through it in 1 µs ? Ans: V1= 5V How much current will flow through a 0.1- µF capacitor if turning off a logic gate creates a 100 mV voltage spike across the capacitor in 1 ns ? Ans: ic=10A
