Acircuit consists of a 9.0 mh inductor coil, a 230 ω resistor, a 12.0 v ideal battery, and an open switch-all connected in series. the switch closes at time t = 0. what is the initial rate of change of the current - i just after the switch closes? dt l=0 a/s what is the steady-state value of the current if a long time after the switch is closed? if= at what time 185% does the current in the circuit reach 85% of its steady-state value? 185% = what is the rate of change of the current when the current in the circuit is equa dt li=1; /2 its steady-state value? di - dt li=1; /2
