6 FAQs about [How capacitor energy storage changes]
How does a capacitor store energy?
The voltage on the capacitor is proportional to the charge Storing energy on the capacitor involves doing work to transport charge from one plate of the capacitor to the other against the electrical forces. As the charge builds up in the charging process, each successive element of charge dq requires more work to force it onto the positive plate.

How much electricity can a capacitor store?
The amount of electrical energy a capacitor can store depends on its capacitance. The capacitance of a capacitor is a bit like the size of a bucket: the bigger the bucket, the more water it can store; the bigger the capacitance, the more electricity a capacitor can store. There are three ways to increase the capacitance of a capacitor.
How do you find the energy stored in a capacitor?
The energy stored in a capacitor can be expressed in three ways: Ecap = QV 2 = CV2 2 = Q2 2C E cap = QV 2 = CV 2 2 = Q 2 2 C, where Q is the charge, V is the voltage, and C is the capacitance of the capacitor.
