In the circuit below, the voltage source is a 5 v power supply. the inductor is considered to be ideal (it has no internal resistance) and large (say, 1 henry). r1 = 2.5 ω and r2 = 2.5 ω . part a assume the switch had been closed for a long time. use the loop rule to determine the voltage drop across r2. nothing v request answer part b at the instant just after the switch was opened, what is the current though the inductor? nothing a request answer part c at the instant just after the switch was opened, what is the current though r2? nothing a request answer part d at the instant just after the switch was opened, what the current though r1? nothing a request answer part e at the instant just after the switch was opened, what the magnitude of the voltage drop across r1? nothing v request answer part f suppose r1 were replaced with a resistor with 10 times the resistance and the switch had been closed for a long time. what would the magnitude of the voltage drop across r1 be just after the instant in which the switch was opened?
