Q: What is the energy stored in a capacitor with capacitance C charged to a voltage V?
Solution:
The energy (U) stored in a capacitor is given by the formula U = 1/2 CV².
Steps: 6
Show Steps
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: U = 1/2 CV².
Step 5: Identify that in this formula, you multiply the capacitance (C) by the square of the voltage (V²) and then divide by 2.
Step 6: Use the formula to calculate the energy stored by plugging in the values for C and V.
