To determine the electric charge using electric potential and electric capacitance, we can use the following formula:

Q = CV

Where Q is the electric charge, C is the electric capacitance, and V is the electric potential.

Electric charge is a fundamental quantity in physics that represents the amount of electrical energy stored in an object. Electric potential, also known as voltage, is a measure of the electrical potential energy per unit charge in a circuit. Electric capacitance is a measure of the ability of an object to store an electrical charge.

To find the electric charge, we can multiply the capacitance of the object by its electric potential. This formula is commonly used in electrical engineering and physics to calculate the amount of electrical energy stored in a capacitor.

In real-world applications, this formula is used in the design and construction of electrical circuits, such as in the development of electronic devices like smartphones and computers. Electrical engineers and physicists use this formula to determine the amount of energy stored in a capacitor and to design circuits that can efficiently store and transmit electrical energy.

An alternative formula for determining the electric charge can be derived from:
\(C\) \(=\) \(\dfrac{Q}{V}\)
\(Q\): The electric charge
\(C\): the electric capacitance
\(V\): the voltage
The SI unit of electric charge is: \(coulomb\text{ }(C)\)
