Questions & Step-by-Step Solutions
A capacitor is charged to a voltage V. What is the energy stored in the capacitor?
Step 1: Understand that a capacitor stores energy when it is charged to a voltage (V).
Step 2: Identify the formula for the energy (U) stored in a capacitor, which is U = 1/2 CV^2.
Step 3: Recognize that 'C' represents the capacitance of the capacitor, and 'V' is the voltage it is charged to.
Step 4: To find the energy stored, you need to know the values of C and V.
Step 5: Plug the values of C and V into the formula U = 1/2 CV^2.
Step 6: Calculate the result to find the energy stored in the capacitor.
Energy Stored in a Capacitor – The formula U = 1/2 CV^2 represents the relationship between the energy stored (U), capacitance (C), and voltage (V) in a capacitor.
