Questions tagged [transient]
A change in an electrical system from an equilibrium or steady state. The response of the electrical system to a transient is its transient response. Examples of transients include load transients (in which the load suddenly changes) and line transients (in which the input voltage of an electrical system suddenly changes). The electrical system may require protection from certain transients, e.g. by using transient-voltage-suppression (TVS) diodes.

How do I estimate the max current of a series RLC circuit during transients?
I have a series RLC circuit with an applied voltage of
$$
v(t) =
\begin{cases}
V_{DC}+V_{AC}sin(\omega_s t), & t\ge0 \\
0, & t<0
\end{cases}
$$
I want to know what the worst case current ...

How will the voltage across the series capacitor vary?
At t=0, due to the infinite frequency of the step, the network will reduce to a series to 2 capacitors and both will get charged. The capacitor to the left of X has a polarity such that it gets ...
