6 FAQs about [Capacitor power conservation law]
What is the law of power conservation?
The law of power conservation states that..If the magnitude of the power of an individual component in a circuit increases to a certain amount then there should be some compensatory change by the same amount in power of another component to maintain the overall power of the circuit constant.
What is energy stored in a capacitor?
Energy stored in the large capacitor is used to preserve the memory of an electronic calculator when its batteries are charged. (credit: Kucharek, Wikimedia Commons) Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q Q and voltage V V on the capacitor.
How do you calculate the energy stored in a capacitor?
You should be comfortable linking the two equivalent ideas - the energy stored in the capacitor is equal to the work done on it, by the power supply which charges it. Make sure you can apply each of the three equations given above! Area = × base × height The area under a potential difference-charge graph represents the energy stored by a capacitor

What is the energy stored in a capacitor ECAP e cap?
The average voltage on the capacitor during the charging process is V /2 V / 2, and so the average voltage experienced by the full charge q q is V /2 V / 2. Thus the energy stored in a capacitor, Ecap E cap, is where Q Q is the charge on a capacitor with a voltage V V applied. (Note that the energy is not QV QV, but QV/2 QV / 2.)
Why do capacitors have a conservative field?
This question is quite a common one for those first learning about capacitors. First, let's remember that an electric field caused by stationary charges is conservative--this can easily be explained sincea single charge creates a conservative field, and superposition of two conservative fields creates another conservative field.
