RC Discharging Circuit Tutorial & RC Time Constant
In this experiment, instead of merely discharging an already charged capacitor, you will be using an Alternating Current (AC) "square wave " voltage supply to charge the capacitor …
Charge q and charging current i of a capacitor The expression for the voltage across a charging capacitor is derived as, ν = V(1- e -t/RC) → equation (1). V – source voltage ν – instantaneous voltage C– capacitance R – resistance t– time The voltage of aV = Q.
My contribution is to point out a circuit that suits your title: "A path for capacitor''s charging, and another for discharging it" is a solution commonly used to drive a N-channel mosfet/IGBT in the configuration high-side (load grounded). This avoids the use of P ...

Likewise, a similar argument can be made for the positive plate regarding how easy it is to either remove or add electrons to that plate as the capacitor is charging or discharging. Note that there are many instances in nature of a rate depending on how much of some substance or energy already exists (e.g., Newton''s Law of cooling), and for that …
Charging and discharging of a capacitor 67 off) the capacitor gets discharged through the load. The rate at which the charge moves, i.e. the current; this, of course, will depend on the resistance offered. It will be seen, therefore, that the rate of energy transfer will

Charging and Discharging Capacitive Circuits The voltage on a circuit having capacitors will not immediately go to its settling state unlike purely resistive circuits. When a potential difference is applied to an RC circuit the like of Figure 31 below and then S1 is closed, the voltage across the capacitor will exponentially rises from zero
