Devices used to open an electrical circuit are called OCPD's. (overcurrent protection devices) The most common are circuit breakers and fuses. In commercial motor starters they often employ another OCPD called a "heater" (UK thermal fuse) which is a metal strip which melts like the element in a small fuse when too much current (amps) go through it. They devices are in the circuit primarily to protect the wiring and devices they power. Circuit breakers such as in your home panel do protect you from a "shorted" circuit. Another safety and most common in residences are GFCI's or ground fault circuit interrupters (UK ELCB, Earth Leakage Circuit Breaker or RCD, Residual Current Detector) which come as both a receptacle (female plug) or as a circuit breaker.
A measurement of electricity. Discovered by George Ohm. Ohm being his last name. Not an abbreviation. A measurement of electrical current resistance based per 1 amp of current flow.
dear sir, Please issue me no objection certificate for change name of electricity bill.
A capacitor nominally has no inductance, which is lucky because there is no such device to mesure it with.

If this question is asking about the box supplied by your utility company which counts the kilowatt.hours you used, so they can send you a bill for electricity, it is called an electricity meter. If you are asking about the name of the standard unit used to measure a quantity of electricity used, it is called the kilowatt.hour (or k.Wh for short.)
An insulator is a material that stops or reduces the flow of electricity.
That doesn't require any special device - it is part of the natural interaction between electricity and magnetism. However, devices that make practical use of this include electric motors, and generators.
Anode The name for a positive charge conductor through which electrons flow into a device is called the life conductor.
A remote racking device is the name of a safety device that is fitted to ensure a circuit breaker cannot be racked out when closed.
Wind turbine.
A substance that lets electricity flow through it is called a conductor (or sometimes, to be more explicit, it is called an electrical conductor). Substances which do not permit the flow of electricity are called insulators.
tourniquet
it is called a PC a pasific name as a macbook
A diode does that.

Something wound in the form of a helix or spiral.Common name for any intra-uterine contraceptive device (Abbreviation: IUD)-the first IUDs were coil-shaped.(electrical) A coil of electrically conductive wire through which electricity can flow.
