Physics: Electricity and Magnetism: RL Circuits
In the circuit below, the voltage source is a 5V power supply. The inductor is considered to be ideal (it has no internal resistance) and large (say. 1 henry) R1 = 5 Ohm and R2 = 20 Ohm Units are required in all numerical answers. Assume the switch had been closed for a long tune. Use irchhoff s rules to determine the voltage drop across R2. V2= At the instant just after the switch was pened, what is the current though the inductor? IL= At the instant just after the switch was opened, what is the current though R2? IL= At the instant just after the switch was opened, what the current though R1? IL= At the instant just after the switch was opened, what the magnitude of the voltage drop across R1? Vt= Suppose Ri were replaced with a 50 Ohm resistor and the switch had been closed for a long tune What would the magnitude of the voltage drop across be just after die mstant in which the switch was opened? With R1 = 50 Ohm V1 =Explanation / Answer
