Equation 6.1.2.6 6.1.2.6 provides considerable insight into the behavior of capacitors. As just noted, if a capacitor is driven by a fixed current source, the voltage across it rises at the constant rate of i/C i / C. There is a limit to how quickly the voltage across the capacitor can change.
The energy stored in a capacitor is proportional to the capacitance and the voltage. When it comes to electronics, the significant components that serve as the pillars in an electric circuit are resistors, inductors, and capacitors. The primary role of a capacitor is to store a certain amount of electric charge in place.
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
When a voltage is applied to a capacitor, it starts charging up, storing electrical energy in the form of electrons on one of the plates. The other plate becomes positively charged to balance things out. This charge separation creates a voltage potential between the two plates and an electric field between the plates, storing the energy.
Tune a radio into a station, take a flash photo with a digital camera, or flick the channels on your HDTV and you're making good use of capacitors. The capacitors that drift through the sky are better known as clouds and, though they're absolutely gigantic compared to the capacitors we use in electronics, they store energy in exactly the same way.
There is a limit to how quickly the voltage across the capacitor can change. An instantaneous change means that dv/dt d v / d t is infinite, and thus, the current driving the capacitor would also have to be infinite (an impossibility). This is not an issue with resistors, which obey Ohm's law, but it is a limitation of capacitors.
6.1.2: Capacitance and Capacitors
Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor.
