The capacitance of a parallel plate capacitor without any medium between its plates is given by When a dielectric completely fills the space between the plates of the capacitor, the capacitance increases K times, where K is the dielectric constant (relative permitivity) of the dielectric. If a dielectric slab of thickness t (<d) is introduced…… Continue reading EFFECT OF DIELECTRIC IN A CAPACITOR
Mohit asked this question: “What is meant by charge on a capacitor?” Answer: As we know, a simple capacitor (say a parallel plate capacitor) consists of two plates parallel to each other. When charged, charge on either plate of the capacitor is called charge on the capacitor. The following links will help you explore further…… Continue reading What is meant by charge on a capacitor?
Capacitance is the property of an electric conductor that characterizes its ability to store an electric charge. An electronic device called a capacitor is designed to provide capacitance in an electric circuit by providing a means for storing energy in an electric field between two conducting bodies.
