Question
For the circuit (below) , take E = 600 V , R1=4.0k?, R2=6.0k? and assume the capacitor is initially uncharged.
1) What are the currents in both resistors just after the switch is closed? (i1 and i2)
2) What is the voltage across the capacitor just after the switch is closed? (Vc)
3) What are the currents in both resistors a long time after the switch is closed? (i1 and i2)
4) What is the voltage across the capacitor a long time after the switch is closed? (Vc)
5) Long after the switch is closed it's again opened. What are I1, I2 just after this switch opening?
6) What is VC just after this switch opening?
7) What are I1, I2 a long time later?
8) What is VC a long time later?
Explanation / Answer
1) I1=150 amp
I2= 0
2) zero
3) I1=I2= 60 amp
4) V=360 volt
5) I1= 0
I2= 60 amp
6) 360 Amp
7) I1=I2= 0
8) VC=0
