RC transients

2nd law of commutation.



Uc = Us mouth + Uc cv

Uc mouth = E


τ = RC - characterizes the speed of the transition process. The transition process will end in about (3 ÷ 5) τ. Unlike the voltage, the current on the capacitor changes abruptly.


The key is open





the current in the RC circuit is limited only by the resistance.
