Questions & Step-by-Step Solutions

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).
