Electrical Glossary

1. the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane
4. an electromotive force or potential difference expressed in volts.
5. a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.
7. an apparatus for reducing or increasing the voltage of an alternating current.
8. a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power.
10. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
11. the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.

1. a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this.
2. the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
3. relating to or determined by the sun.
4. an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
6. the capacity or ability to direct or influence the behavior of others or the course of events.
9. a closed path that allows electricity to flow from one point to another. It may include various electrical components, such as transistors, resistors, and capacitors, but the flow is unimpeded by a gap or break
