Capacitor Discharge Formula Rc. O 10v and is then discharged through an r 10ωresistor as shown. Immediately after the switch is closed the initial current is io v.
D calculate the capacitor voltage after 100s. When t rc v v o e 0 37 v o and the product rc is known as the time constant for the circuit. We already got the time constant from point a.
Where voltage across the resistor is different and represented by the following formula.
Q q o e t rc v v o e t rc and also i i o e t rc q q o e t rc you should realise that the term rc governs the rate at which the charge on the capacitor decays. The formula for capacitor voltage is vc v 1 e t rc. When t rc v v o e 0 37 v o and the product rc is known as the time constant for the circuit. D calculate the capacitor voltage after 100s.
