Lesson: Energy Stored in Capacitors High School Physics

Physics

In this lesson, we will learn how to relate the capacitance of and voltage across parallel-plate capacitors to the charge and energy stored in them.

Worksheet

Q1:

Which of the following formulas correctly relates the energy stored by a parallel plate capacitor to the charge stored by the capacitor and the capacitance of the capacitor?

Q2:

Which of the following formulas correctly relates the energy stored by a parallel plate capacitor to the charge stored by the capacitor and the potential difference across the plates?

Q3:

A 415 nF capacitor stores 162 µC of charge. How much electrical potential energy is stored in the capacitor?
