# Capacitor Energy Storage Formula: Understanding the Basics

#### By R.W. Hurst, Editor

Capacitors are important components in electronic circuits for energy storage. The formula for charge storage by a capacitor and the formula for calculating the energy stored in a capacitor demonstrate that the amount of charge and energy stored in a capacitor is directly proportional to its capacitance and the voltage applied to it. The capacitance and voltage of a capacitor affect its energy storage capability and capacity, respectively. When discharged, a charged capacitor can deliver a large shock of electrical energy, which can be dangerous and potentially lethal.

The Formula for Charge Storage by Capacitor

The amount of electrical charge that a capacitor can store is directly proportional to the applied voltage and the capacitance of the capacitor. The formula for charge storage by the capacitor is given by:

Q = C x V

Where Q is the charge stored in coulombs, C is the capacitance in farads, and V is the voltage across the capacitor in volts.

Calculating Energy Stored in a Capacitor

The energy stored in a capacitor can be calculated using the formula:

E = 1/2 x C x V^2

Where E is the energy stored in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.

The Stored Energy of a Capacitor

When a capacitor is charged, electrical energy is stored in the electric field between its two plates. The stored energy of a capacitor can be released when the capacitor is discharged. The amount of energy that can be stored in a capacitor is directly proportional to the capacitance and the voltage across the capacitor. Therefore, when discharged, a charged capacitor can deliver a large shock of electrical energy, which can be dangerous and potentially lethal.

Calculating Energy Stored

The energy stored in a capacitor is a function of its capacitance, and the voltage applied. The formula for calculating the energy stored is given by:

E = 1/2 x C x V^2

Where E is the energy stored in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.

Formula for Calculating Energy Stored in a Capacitor

The formula for calculating the energy stored in a capacitor is given by:

E = 1/2 x C x V^2

Where E is the energy stored in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts. This formula demonstrates that the energy stored in a capacitor is directly proportional to the capacitance and the square of the voltage applied to it.

Capacitance and Energy Storage Capability

The capacitance of a capacitor affects its energy storage capability. A capacitor with a higher capacitance can store more energy than a capacitor with a lower capacitance. This is because the amount of charge a capacitor can store is directly proportional to its capacitance.

Voltage and Energy Storage Capacity

The voltage across a capacitor affects its energy storage capacity. A capacitor with a higher voltage applied to it can store more energy than a capacitor with a lower voltage applied to it. This is because the energy stored in a capacitor is directly proportional to the square of the voltage applied.
