The energy stored in a capacitor is directly proportional to which of the following? (2023)

The energy stored in a capacitor is directly proportional to which of the following? (2023)

Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
Step 2: Learn the formula for energy stored in a capacitor, which is U = 1/2 CV^2.
Step 3: Identify the variables in the formula: U is the energy, C is the capacitance, and V is the voltage.
Step 4: Notice that the formula shows energy (U) depends on the square of the voltage (V^2) and the capacitance (C).
Step 5: Conclude that the energy stored in a capacitor is directly proportional to both the capacitance (C) and the square of the voltage (V^2).

Energy in Capacitors – The energy stored in a capacitor is calculated using the formula U = 1/2 CV^2, indicating that it is directly proportional to the capacitance (C) and the square of the voltage (V).
Proportional Relationships – Understanding how changes in voltage and capacitance affect the energy stored in a capacitor.
