Question

In the circuit on the figure, determine the current in each resistor (I1,I2,I3) at the following moments:

Part A

When the switch is closed.

Express your answers in terms of some or all of the variables E, R1, R2, R3. Enter your answers separated by commas.

Part B

A long time after the switch is closed.

Express your answers in terms of some or all of the variables E, R1, R2, R3. Enter your answers separated by commas.

Part C

After the switch has been closed for a long time, and then reopened, what is each current just after it is opened?

Express your answers in terms of some or all of the variables E, R1, R2, R3. Enter your answers separated by commas.

Part D

After the switch has been closed for a long time, and then reopened, what is each current after a long time?

Express your answers in terms of some or all of the variables E, R1, R2, R3. Enter your answers separated by commas.

Note: All the "E" notations refer to the figure. Thank you!!

I1,I2,I3 =

1) i1=i2=e/(r1+r2) i3=0

2) i1=e/(r1+(r2//r3)) i2={e(r2//r3)/(r1+(r2//r3))}/r2 i3={e(r2//r3)/(r1+(r2//r3))}/r3
