Power Engineering

A device that stores electricity for future use.

Converting other forms of power into electric power.

lamp that burns a filament in a vacuum in a glass bulb.

Unlike charges attract each other and like charges repel each other.

Any gas fuel derived from the decay of organic matter, as the mixture of methane and carbon dioxide produced by the bacterial decomposition of sewage, manure, garbage, or plant crops. Answer key:

A barrier to obstruct the flow of water, esp. one of earth, masonry, etc., built across a stream or river.

A wind generator; wind plant.

A substance that allows electricity to pass through it.

When an electrical current is produced without any physical connection between the two parts of the circuit.

Electric current that changes direction continually.

The act or process of burning.

To bring under conditions for effective use the power of seas; gain control over for a particular end.

A form of energy associated with the presence and movements of electrical charges.

A path electricity follows, from a source through a connection to an output device.

Any combustible organic material, as oil, coal, or natural gas, derived from the remains of former life.

Involves taking power from the transmission system to end users, converting it to voltages at which it is ultimately required.

Includes moving power over somewhat long distances, from a power station to near where it is used.

Electricity that is "at rest" or static until it is discharged.

Gum or resin from trees that has fossilized and turned solid.

A subfield of electrical engineering that deals with the generation, transmission and distribution of electricity as well as the design of a range of related devices like: transformers, electric generators, electric motors and p

The relationship, in a circuit using direct current, among voltage, current and resistance: One volt of electricity (E) is needed to force one ampere of current (I) through one ohm of resistance (R).

The physics of the electromagnetic field; a field encompassing all of space which exerts a force on particles that possess the property of electric charge, and is in turn affected by the presence and motion of those particles.

A unit that measures the current.

Electric current that flows only in one direction, such as that supplied by a battery.

An arrangement of interrelated objects or items of equipment for accomplishing a particular task

The amount of electrical energy stored in a battery, capacitor, or any insulated object that can hold energy for a time.

An oily, thick, flammable, usually dark-colored liquid that is a form of bitumen or a mixture of various hydrocarbons, occurring naturally in various parts of the world and commonly obtained by drilling.

The push or pull of magnets, which are electrically charged with poles attracted to the North Pole or South Pole.

The unit of measure of electrical force, named after Alessandro Volta, the inventor of the battery.

An electric device consisting essentially of two or more windings wound on the same core, which by electromagnetic induction transforms electric energy from one set of one or more circuits to another set of one or more circuits.

A type of iron ore with a silvery finish, sometimes called magnetite.

The unit of measure of electrical charge.

A material that does not conduct electricity, or in other words, doesn't allow electricity to pass through it.
