The energy possessed by a object by virtue of its position or its configuration is called its potential energy.
Concept of potential energy is valid only in conservative field. In conservative force field when a object moves on a round trip then its kinetic energy will not change. But if we assume a point B on the path, then at point B, its kinetic power will not be equivalent as at point A. (Let K.EB < K.EA), we may say that this changes in kinetic energy has stored in configuration of system and this kept energy is known as potential energy of system
Define Ohm's Law Ohm's Law: Relationship among the potential difference across an electric device and the current that runs by it. V= I.R
Explain the term 'resistivity' and write its S. I . unit. Derive the expression for the resistivity of a conductor in terms of number density of free electrons and relaxation time.
Primary cell Is that cell in which electrical energy is produced because of chemical energy. In the primary cell, chemical reaction is irreversible. This cell cannot be recharged.
give me full detail about not gate i.e its logic symbol, truth table etc
