About Close the switch when the capacitor has stored energy
For t<0, we know that vc (t)=Vo; closing the switch at t=0 allows current to flow in the circuit, as stored energy from the capacitor is released and dissipated as heat in the resistor. The capacitor voltage exponentially decays with time, asymptotically approaching zero.

After closing the switch, the charge redistributes between the two capacitors. I am trying to show that half of the initial energy stored in the capacitors is dissipated. The initial energy stored in the charged capacitor is: $$ E_ {initial} = \frac {1} {2} C_1 V^2 $$ After the switch is closed.
The energy delivered by the defibrillator is stored in a capacitor and can be adjusted to fit the situation. SI units of joules are often employed. Less dramatic is the use of capacitors in microelectronics to supply energy when batteries are charged (Figure \ (\PageIndex {1}\)). Capacitors are.
Closing the switch in the circuit allows charge Q to redistribute between two capacitors, one with capacitance C and another with capacitance 3C, reaching equilibrium. The final potential difference across both capacitors is V_C = Q/4C, as they are effectively in parallel. The charge on the C.
Capacitors are critical components that can store electrical charge, diminishing the rapid changes in voltage that might occur when a switch alters the circuit state. The ability of a capacitor to temporarily retain energy allows it to act as a buffer, regulating the flow of electricity as it.
