So if I1=ε/22 then V1=(ε/22)R1 and V2=V3=ε-(ε/22)R1 I2=[(ε-(ε/22)R1]/R2 I3=[(ε-(ε/22)R1)]/R3 For part c, I know that inductor has maximum current through it right after switch opens then current slowly decreases to zero with equation Ifinal=Iinitial*e-t/τ. So I guess the currents will be...

So the time constant is τ=-t/ln(Ifinal/Iinitial) There is no value for part c?

For part a, the inductor will have very high resistance so no current will flow through R3. The current of R1 and R2 will be I1=I2=ε/30Ω. Yes, that's right. If the value for ε is not supplied in the problem statement then you'll have to answer symbolically (with a formula that includes ε as...

R2 is in parallel with the inductor. I know that current decrease is represented by I(final)=I(initial)*e^(-t/τ).

After a long time, the inductor will act like a piece of wire with no resistance so current would still be flowing through R1 but zero current would be in R2. The current in R1 would be I=10/10=1 A. Am I correct? For part c, I know that the time constant is tau=L/R so do I just use L=2.0 H and...

Homework Statement For the circuit given that R1=10 W, R2=20 W, R3=30 W and L=30 mH, determine the current through each resistor a) at the moment the switch is closed b) a long time after the switch is closed After the switch has been closed a long time it is reopened, determine the...

Homework Statement For the circuit below, if L=2.0 H, emf=10 V, R1=10 ohms, R2= 20 ohms, what is the current through each component a) at the instant the switch is closed b)a long time after the switch is closed c) If after a long time the switch is reopened, what is the time constant...
