The capacitor would start discharging. Is it the electrons we care about here rather than the actual "current"? Because the electrons would go through R2. The "current" doesn't go through anything. The weird thing about these problems is that I've never actually had to apply the concept ...
t = time constant in seconds t = time in seconds The current of a discharging capacitor can be approximated by a decaying exponential function of time. Time Constant FIGURE 2.5 The decaying exponential. Since the exponential factor only approaches zero as t increases without limit, such functions...

The meaning of DISPLACEMENT CURRENT is a limited shifting of electric components that occurs within a dielectric when a voltage is applied to or removed from it (as in charging or discharging a capacitor) and that corresponds to the current in the circui
摘要: PROBLEM TO BE SOLVED: To obtain a charging/discharging current measuring apparatus for an electric double-layer capacitor capable of measuring the current to/from an electric double-layer capacitor in real time with a simple circuit constitution and high efficiency....
The additional pre-charging equipment and maintenance of capacitor voltage also increase the cost and control difficulty of the circuit breaker. On this basis, a controllable capacitor commutation based superconducting DC circuit breaker (CCCB-SDCCB) is newly proposed in this paper. Unlike traditional...
A switching regulator for converting input voltage to output voltage includes a switch; an inductor energized by input voltage by the switch; a rectifier for discharging the inductor; and a slope voltage generator for generating slope voltage inclined responsive to current of the inductor, amplifies ...
