Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the process of a liquid flowing in narrow spaces without the assistance of, or even in opposition to, external forces like gravity.

The average expected output of a generator.

The amount of output from a power source that may be statistically relied upon, practically the minimum power within a longer period, usually expressed as a percentage of the nominal power.

Capacitance is the ratio of the amount of electric charge stored on a conductor to a difference in electric potential.

A harder or more resistant rock type overlying a weaker or less resistant rock type.

The CANDU (Canada Deuterium Uranium) is a Canadian pressurized heavy-water reactor design used to generate electric power.

The candela is the base unit of luminous intensity in the International System of Units (SI). The SI unit symbol is cd.

A recording device that records the amount of sunshine at a given location or region at any time.

A calorimeter is an object used for the process of measuring the heat of chemical reactions or physical changes as well as heat capacity.

The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions.

The calorie is a unit of energy defined as the amount of heat needed to raise the temperature of a quantity of water by one degree.

Cadmium telluride (CdTe) photovoltaics describes a photovoltaic (PV) technology that is based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity.

In the electrical wiring of buildings, a cable tray system is used to support insulated electrical cables used for power distribution, control, and communication.

The point at which the submarine cable connects into the land-based infrastructure or network.

A cable landing point is the location where a submarine or other underwater cable makes landfall.

A cable harness, also known as a wire harness, wiring harness, cable assembly, wiring assembly or wiring loom, is an assembly of electrical cables or wires which transmit signals or electrical power.

Currents which are a result of capacitance in the cables.

A cable assembly is the composition of one or more electrical cables and their corresponding connectors.

A small single cell battery shaped as a squat cylinder resembling a button.

A butterfly valve is a valve that isolates or regulates the flow of a fluid.
