Capacitors Explained
While trying to solve questions involving impulses and step functions, we are supposed to assume that an uncharged capacitor or an uncharged inductor acts as a short circuit and open-circuit respec... $begingroup$ A current impulse (infinite di/dt) can only pass through a perfect inductor if the terminal voltage across the inductor is infinite.
Then we can see that at DC a capacitor has infinite reactance (open-circuit), at very high frequencies a capacitor has zero reactance (short-circuit). Capacitance in AC Circuits Example No1 Find the rms current flowing in an AC capacitive circuit when a 4μF capacitor is connected across a 880V, 60Hz supply.
This paper presents experimental results on 750 V and 1200 V SiC MOSFETs stressed under short-circuit (SC) type I conditions using two different test methods: incremental SC pulses until failure and a single SC pulse to failure. These two methods result in different values for short-circuit withstand time (tSCWT). TCAD …

RC or resistor-capacitor circuits are a basic type of circuit. The charging or discharging of a capacitor requires time, and different capacitors have different charging times. The RC time constant is the fixed time interval which is equal to the resistance times the capacitance in a series RC circuit.
