Homework Answers
after a long time Switch is closed ast S1,
Both Capactors will be at Sereis Combination and Both Resistors
so
Rnet = R1+R2 = 680+220 = 900 ohms
Cnet = C1C2/(C1/+C2)
Cnet = 220* 330/(220+330)
Cnet = 132 uF
so
intial charge Qi = CV = 132e -6 * 72 = 9.5 mC
Current i = V/R = 72/(900) = 0.08 Amps
initial Volatge 72 Volts
--------------------------------------
yes when switch is closed,
growth of charge takes place across the terminals of the Capacitor
so across C2 in increases

In the circuit shown in (Figure 1) switch Si has been closed a long time while switch S2 has been left open. Then S2 is closed at the same instant when S1 is opened.
In the circuit shown in (Figure 1) switch Si has been closed a long time while switch S2 has been left open. Then S2 is closed at the same instant when S1 is opened.Part A Just after S2 is closed, the current through the resistor is 12.0 A and its rate of decrease is di/dt = 36.0 A/s. How long does it take the current to decrease to Figure 1 of 1 6.00 A, one-half its initial value?
