An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit.

Electrocution is death or severe injury by electric shock, electric current passing through the body.

The transformation of chemical energy into electricity as in batery.

Electrochemical engineering is the branch of chemical engineering dealing with the technological applications of electrochemical phenomena, such as electrosynthesis of chemicals, electrowinning and refining of metals, flow batteries and fuel cells, surface modification by electrodeposition, electrochemical separations and corrosion.

Electrochemical energy conversion is a field of energy technology concerned with electrochemical methods of energy conversion including fuel cells and photoelectrochemical. This field of technology also includes electrical storage devices like batteries and supercapacitors.

An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to cause chemical reactions.

Electrification is the process of powering by electricity changing over from an earlier power source.

Electricity retailing is the final sale of electricity from generation to the end-use consumer.

An electricity meter or energy meter is a device that measures the amount of electric energyconsumed by a residence, a business, or an electrically powered device.

In economic terms, electricity is a commodity capable of being bought, sold, and traded.

Electricity generation is the process of generating electric power from sources of primary energy.

The combined transmission and distribution network is part of electricity delivery, known as the electrical grid.

A small floating hydroelectric power plant anchored to the ground in a river.

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.

Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.

A transient fault is a fault that is no longer present if power is disconnected for a short time and then restored; or an insulation fault which only temporarily affects a device's dielectric properties which are restored after a short time.

In electronics, electrical termination is the practice of ending a transmission line with a device that matches the characteristic impedance of the line.

Electrical tape (or insulating tape) is a type of pressure-sensitive tape used to insulate electrical wires and other materials that conduct electricity.

A symmetric or balanced fault that affects each of the phases equally.

Electrical susceptance (B) is the imaginary part of admittance, where the real part is conductance. In SI units, susceptance is measured in siemens.
