Voltage Across Capacitor After Switch Is Closed

You have the right general idea but you cant just consider the two capacitors as one 3f capacitor. The switch is closed and charge flows until equilibrium is reestablished ie until both capacitors have the sam voltage across their plates.

Just before the switch is closed the 2f capacitor will be fully charged and i presume the 1f capacitor is fully discharged.

Voltage across capacitor after switch is closed. When the switch is closed the current would be flowing through r1 and r2. Circuit behavior described by kirchhoffs rules. I have attached a jpg of the drawing 2.

C initially uncharged and then switch s is closed. What is the voltage across the capacitor after a long time. S i in s i out s closed and c charges to some voltage with some time constant strategic analysis.

Given the circuit above the instant that the switch is closed the voltage across the capacitor is00 v30 v15 v75 v given the circuit above the instant that the switch is closed the voltage across the resistor is30 v75 v15 v00 v given the circuit above a long time after the switch is closed the voltage across the. So when the switch is closed the 2f capacitor will discharge and the 1f capacitor will charge. In the given circuit when the switch is closed some current will still flow through certain components even when the capacitor has reached its peak voltage and its current is zero.

The attempt at a solution i know the capacitors are in series so i. Vc 0 vc v vc 2v3 2 what is the voltage across the capacitor after switch s1 has been closed for a very long time. Vc 0 vc v vc 2v3 3 after being closed a long time switch 1 is opened and switch 2 is closed.

What current still flows in the circuit. S v drops 0 kcr. Find the resulting voltage across either capacitor.
