How to Calculate Energy Stored in a Capacitor

What is the formula to calculate the energy stored in a capacitor?

Choose the correct formula:

a. E = ½CV²

b. E = CV²

c. E = ½C/V

The formula to calculate the energy stored in a capacitor is:

a. E = ½CV²

When calculating the energy stored in a capacitor, we use the formula E = ½CV². This formula takes into account the capacitance (C) of the capacitor and the voltage (V) across it. By plugging in the values for capacitance and voltage, we can determine the amount of energy stored in the capacitor.

In this case, the energy stored in a capacitor can be calculated using the formula E = ½CV², where E is the energy in joules, C is the capacitance in farads, and V is the voltage in volts. Ensure to use the correct units for capacitance and voltage to get the accurate result.

Understanding how to calculate the energy stored in a capacitor is essential for various applications in electronics and electrical engineering. By mastering this formula, you can effectively manage the energy stored in capacitors and optimize their performance in circuits.
