10. One application of an RL circuit is the generation of time - varying high voltage from a low - voltage source as shown in Figure . ( a ) What is the current in the circuit a long time after the switch has been in position a ? ( b ) Now the switch is thrown quickly from a to b . Compute the initial voltage across each resistor and across the inductor . ( c ) How much time elapses before the voltage across the inductor drops to 12 V ? a + i ( t ) Lā ele M 12.0 V La S b i ( t ) Leg 2.00 H 1200 Q 12.0 Q
