Capacitor Energy Calculator
What is Energy Stored in a Capacitor?
A capacitor is an electrical component that stores energy in the form of an electric field when a voltage is applied across its terminals. The energy stored in a capacitor depends on two main factors: the capacitance of the capacitor and the voltage applied to it. This stored energy can later be released into a circuit when required.
Formula for Energy Stored in a Capacitor
The energy stored in a capacitor is calculated using the formula:
E = ½ × C × V²
Where:
E = Energy stored (Joules)
C = Capacitance (Farads)
V = Voltage across the capacitor (Volts)
How to Use This Capacitor Energy Calculator
1. Enter the value of capacitance in farads.
2. Enter the voltage applied across the capacitor.
3. Leave the energy field blank.
4. Click on Calculate to instantly find the stored energy.
Alternatively, you can enter energy and one of the other parameters to calculate the missing value. The calculated field will be highlighted automatically.
Example Calculation
Consider a capacitor with a capacitance of 100 µF (0.0001 F) connected to a 12 V power supply.
Using the formula:
E = ½ × C × V²
E = ½ × 0.0001 × 12²
E = 0.0072 Joules
This means the capacitor stores 0.0072 joules of electrical energy.
Applications of Capacitor Energy Calculation
Capacitor energy calculations are widely used in power supplies, camera flash units, timing circuits, signal processing, and energy storage systems. Students of physics, electronics, and electrical engineering frequently use this formula during exams, lab experiments, and real-world circuit design.
