Maximum charge of capacitor
8.4: Energy Stored in a Capacitor
As the capacitor is being charged, the charge gradually builds up on its plates, and after some time, it reaches the value Q. To move an infinitesimal charge dq from the negative plate to the positive plate (from a lower to a higher potential), the amount of work dW that must be done on dq is (dW = W, dq = frac{q}{C} dq).
8.2: Capacitors and Capacitance
The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device:
Capacitance in AC Circuits
At 0 o the rate of change of the supply voltage is increasing in a positive direction resulting in a maximum charging current at that instant in time. As the applied voltage reaches its maximum peak value at 90 o for a very brief instant in time the supply voltage is neither increasing or decreasing so there is no current flowing through the circuit.
Charging a Capacitor
The charging current asymptotically approaches zero as the capacitor becomes charged up to the battery voltage. Charging the capacitor stores energy in the electric field between the capacitor plates. The rate of charging is typically described in terms of a RC.
What defines the maximum charge a capacitor can store?
The formula for a capacitor discharging is $Q=Q_0e^{-frac{t}{RC}}$ Where $Q_0$ is the maximum charge. But what property defines the maximum charge a capacitor can store? If it depends on capacitance then that means it depends on the voltage you put
