What is the energy stored in a capacitor of capacitance C charged to a potential V? (2021)
Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
Step 2: Know the terms involved. 'C' is the capacitance (how much charge it can store), and 'V' is the voltage (the potential difference across the capacitor).
Step 3: Learn the formula for energy stored in a capacitor. The formula is U = 1/2 CV^2.
Step 4: Break down the formula. 'U' is the energy stored, 'C' is the capacitance, and 'V' is the voltage. The formula means you take half of the capacitance multiplied by the voltage squared.
Step 5: Use the formula. If you know the values of C and V, you can plug them into the formula to find the energy stored in the capacitor.
