Capacitor Charge: Basics, Calculations

Further, the charge time of a capacitor is also mathematically defined by the time constant (τ), a concept that combines resistance and capacitance of the circuit into one metric. The time constant is a measure of how long it takes for the voltage across the capacitor to reach approximately 63.2% of its maximum value in a charging or discharging cycle, …

Capacitor charging and Energy storage

Electrical potential energy is supposedly stored because it takes work to move charge against the electric field (and in fact equal to the work if we set 0 potential energy to an uncharged state). As an analogy, I imagine a capacitor as a spring where "compressing the spring" means adding charge.

Capacitor and Capacitance

A capacitor stores energy through an electrostatic field: unlike charge, which can flow from one point to another, electrostatic fields do not flow from one point of space to another. Standard Units of Capacitance. We major a capacitor in farad. But Farad is a large unit so we major it in sub-units like mili, nano, micro, etc.
