- Efficient
- Accomplishing a task with a minimum of effort and waste. See
Efficiency, Inefficient.
- Electrical circuit
- A closed, conducting path or route through which an electric current travels.
- Electrical (electromagnetic) energy
- Kinetic and potential energy associated with electric charges (e.g.,
electrons) and their movement. See Electrical potential energy.
- Electrical generator
- See Generator.
- Electrical potential energy
- Potential energy stored by separating positive and negative electrical charges against electrical forces. A charged battery has electrical potential energy stored in it. See Electrical (electromagnetic) energy.
- Electric current (also Current)
- A flow of electrically charged particles such as electrons within a conductor or a circuit.See Conduction.
- Electricity
- 1. The behavior of negative and positive charges (electrons and protons) due
to their attraction and repulsion. 2. The flow of electrons; electric current.
See Electrical (electromagnetic) energy, Electric current.
- Electromagnet
- A magnet with a coil of wire that has a current passing through it. The
magnetic field can be made stronger by coiling the wire around an iron core.
- Electron
- 1. A subatomic particle with a negative electric charge that orbits the
nucleus of an atom. 2. The basic particle that makes up an electric current.
- Embodied energy
- The total amount of energy needed to manufacture a finished product from raw
materials, including the energy used to transport the product.
- End use
- A set of devices, products, and systems that use energy for the same or for
similar purposes. Examples of residential end uses include cooking, lighting,
and refrigeration.
