Electrostatics is a branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges with no acceleration. Electrostatics is the study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established. Power circuits are designed to serve a useful function. The mere movement of charge from terminal to terminal is of little use if the electrical energy possessed by the charge is not transformed into another useful form. electrical circuit is simply an energy transformation tool. fuse is nothing more than a short length of wire designed to melt and separate in the event of excessive current. a tube, cord, or the like, filled or saturated with combustible matter, for igniting an explosive. Voltage, electrical potential difference, electric tension or electric pressure (denoted ∆V and measured in units of electric potential: volts, or joules per coulomb) Voltage, also called electromotive force, is a quantitative expression of thepotential difference in electrical charge between two points in an electrical field. Ohm's law states that the current passing through a device is directly proportional to the potential difference applied. Ohm's Law deals with the relationship between voltage and current in an ideal conductor. Powerplant A complex of structures, machinery, and associated equipment for generating electric energy from another source of energy, such as nuclear reactions or a hydroelectric dam. Also called powerhouse, power station. A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path, often where essentially no (or a very low) electrical impedance is encountered Electromagnetic induction (or sometimes just induction) is a process where a conductor placed in a changing
