| lap2 |
to be ahead of (a competitor in a race) by a complete circuit. [2/10 definitions] |
| microchip |
a tiny, usu. silicon, plate of semiconducting material, holding a complicated, electronic, integrated circuit, as in computers. |
| microcircuit |
a miniature electronic circuit, usu. integrated with insulating material as on a silicon chip. |
| microprocessor |
the integrated circuit of a microcomputer, usu. contained on a single silicon chip. |
| motherboard |
the main printed circuit board of a personal computer, which holds chips containing the central processing unit, memory, ports, and the integrated circuits that control the keyboard and other standard peripheral devices, and to which additional circuit boards can be attached. |
| multiplex |
to set up (a circuit) to carry such simultaneous communications. [2/5 definitions] |
| ohm |
a unit of electrical resistance equal to the resistance of a circuit in which an electromotive force of one volt produces a current of one ampere. |
| open circuit |
an electrical circuit that is broken and carries no current. |
| pilot lamp |
a small electric light that indicates, when lit, that current is flowing in an electric circuit. [2 definitions] |
| plug-in |
designed to be connected to an electric circuit. [1/2 definitions] |
| potential |
in an electrical circuit, the difference between the charge at one point and that at another point, which difference results in a flow of current. [1/4 definitions] |
| preamplifier |
a circuit or other device, as in a radio, that electronically identifies and amplifies weak signals before directing them to other amplifiers. |
| printed circuit |
an electric circuit in which the interconnections are formed not by wires but by lines or strips of a conductive material printed, etched, or otherwise deposited on an insulating sheet. |
| push button |
a small button or knob that is pushed, esp. to close or open an electrical circuit. |
| reactance |
in electronics, one of several measurable components of the total resistance in a circuit to the flow of alternating current. |
| relay |
an automatic, usu. electromagnetic, device that activates switches or other devices in the same or another electric circuit when the current or voltage in its own circuit is altered. [1/5 definitions] |
| resistor |
a part of an electric circuit that provides resistance to some of the current. |
| rheostat |
an adjustable resistor used to modulate the amount of electrical current flowing through a circuit. |
| Seebeck effect |
a method of producing an electric current in a circuit with sections made of unlike materials that are caused to have different temperatures. [1/2 definitions] |
| self-induction |
the creation of an electromotive force in a circuit by a varying current in that circuit. |
| short |
a malfunction in an electrical circuit, usu. resulting in a failure; short circuit. [2/16 definitions] |
