CAPACITOR AND CAPACITANCE CLASS 12

Gemini said parallel plate capacitor with dielectric, AI generated Shutterstock Explore A capacitor is essentially a storage tank for electric charge and energy, consisting of two conductors separated by an insulator called a dielectric. Its ability to store charge is measured as capacitance (C= V Q ​ ), where C depends on the physical geometry of the plates and the medium between them. For a standard parallel plate capacitor, this is expressed as C= d ϵ 0 ​ A ​ , and inserting a dielectric material increases this capacity by a factor of K. When arranged in a circuit, capacitors in parallel combine their total capacitance by simple addition (C 1 ​ +C 2 ​ ), whereas in series, they follow a reciprocal sum. The potential energy stored in the resulting electric field is given by U= 2 1 ​ CV 2 , which represents the work done during the charging process.
