The amount of charge a capacitor can store for each volt of potential difference. $C = \frac{Q}{\Delta V}$

A measure of how much a material increases the capacitance of a capacitor when placed between its plates.

A physical constant that represents the ability of a vacuum to permit electric fields. Its value is 8.85 × 10⁻¹² F/m.

The energy stored in a capacitor due to the separation of charge on its plates.

Two conductive plates separated by a small distance, used to store charge and energy.

1. Identify the dielectric constant (κ). 2. Measure the area of one plate (A). 3. Measure the distance between plates (d). 4. Use the formula: $C = \kappa \varepsilon_{0} \frac{A}{d}$

1. Determine the charge (Q) on the capacitor and the potential difference (ΔV) across it, OR determine the capacitance (C) and the potential difference (ΔV). 2. Use the formula: $U_{C} = \frac{1}{2} Q \Delta V$ OR $U_{C} = \frac{1}{2} C (\Delta V)^2$

1. Determine the charge (Q) on each plate. 2. Identify the dielectric constant (κ). 3. Measure the area of one plate (A). 4. Use the formula: $E_{C} = \frac{Q}{\kappa \varepsilon_{0} A}$

The amount of charge a capacitor can store for each volt of potential difference. $C = \frac{Q}{\Delta V}$

Two conductive plates separated by a small distance, used to store equal but opposite charges.

A measure of how much a material increases the capacitance of a capacitor when placed between its plates.

The energy stored in a capacitor due to the separation of charge. $U_{C} = \frac{1}{2} Q \Delta V$ or $U_{C} = \frac{1}{2} C (\Delta V)^2$
