Capacitor Charge Equations. From the relations between charge (Q), capacitance (C) and voltage (V) we can express the capacity charge formula as these three equations: The first shows how to find the capacitance based on charge and voltage, the second is the capacitor charge equation while the third is the capacitor voltage equation.
Simple Equation for Capacitor Charging With RC Circuits
The charge voltage in the capacitor is still zero (Vc = 0) because it was fully-discharged first at t = 0. In this state, the capacitor is a ''short-circuit''. The total current is restricted only by the resistor. With the help of Kirchhoff''s voltage law (KVL), we can calculate the voltage drops in the circuit as:
8.1 Capacitors and Capacitance – University Physics Volume 2
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. 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, …
8.4: Energy Stored in a Capacitor
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). This work becomes the energy stored in the electrical field of the capacitor. In order to charge the capacitor to a charge Q, the total work ...

How to Charge a Capacitor
In this case, the capacitor charges up to 9 volts, since it''s connected to a 9-volt battery. Many of the times while charging a capacitor, a resistor is used in series with the capacitor and voltage source to decrease the amount of current that flows through the capacitor, so that the capacitor isn''t damaged.

Calculating Charge, Voltage, and Current. A capacitor''s capacitance -- how many farads it has -- tells you how much charge it can store. How much charge a capacitor is currently storing depends on the potential difference (voltage) between its plates. This relationship between charge, capacitance, and voltage can be modeled with this equation:

As a result of the repositioning of the charge, there is a potential difference between the two conductors. This potential difference (Delta varphi) is called the voltage of the capacitor or, more often, the voltage across the capacitor. We use the symbol (V) to represent the voltage across the capacitor.

How do capacitors work?
The maximum amount of charge you can store on the sphere is what we mean by its capacitance. The voltage (V), charge (Q), and capacitance are related by a very simple equation: C = Q/V. So the more charge you can store at a given voltage, without causing the air to break down and spark, the higher the capacitance.

DC charging is one of the most common methods of charging capacitors. In this method, a direct current (DC) power source is connected to the capacitor, allowing current to flow from the source into the capacitor. During DC charging, the voltage across the capacitor gradually increases as charge accumulates on its plates.

Capacitance, Charging and Discharging of a Capacitor
The charging voltage across the capacitor is equal to the supply voltage when the capacitor is fully charged i.e. VS = VC = 12V. When the capacitor is fully charged means that the capacitor maintains the constant voltage charge even if the supply voltage is disconnected from the circuit.
