Question: What is the energy stored in a capacitor with capacitance C charged to voltage V?

Options:

Correct Answer: 1/2 CV

Solution:

The energy (U) stored in a capacitor is given by the formula U = 1/2 CV².

What is the energy stored in a capacitor with capacitance C charged to voltage V?

What is the energy stored in a capacitor with capacitance C charged to voltage V?

Step 1: Understand that a capacitor is a device that stores electrical energy.
Step 2: Know that 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 CV².
Step 5: In the formula, C is the capacitance and V is the voltage. You multiply C by the square of V.
Step 6: Finally, multiply the result by 1/2 to find the total energy stored in the capacitor.
