Question: If a capacitor of capacitance C is charged to a voltage V, what is the energy stored in the capacitor?

Options:

Correct Answer: 1/2 CV^2

Solution:

The energy (U) stored in a capacitor is given by the formula U = 1/2 CV^2.

If a capacitor of capacitance C is charged to a voltage V, what is the energy stored in the capacitor?

If a capacitor of capacitance C is charged to a voltage V, what is the energy stored in the capacitor?

Correct Answer: U = 1/2 CV^2

Step 1: Understand that a capacitor is a device that stores electrical energy.
Step 2: Know that the capacitance (C) is a measure of how much charge a capacitor can store per unit voltage.
Step 3: Recognize that voltage (V) is the electrical potential difference across the capacitor.
Step 4: Learn the formula for the energy (U) stored in a capacitor, which is U = 1/2 CV^2.
Step 5: Identify that in this formula, you multiply the capacitance (C) by the square of the voltage (V^2) and then multiply the result by 1/2.
