a solid-state component made from two layers of semiconductor material that allows electric current to flow in only one direction and is commonly used to change alternating current to direct current.

The switched circuit must have its own source of power and is merely routed through the dry contacts. energize-To apply power. fail locked-Refers to an electric lock that requires power to unlock. Also called fail secure. fail unlocked-Refers to an electric lock that automatically unlocks with any power interruption.

In electronics, a diode is a component that restricts the directional flow of charge carriers. Essentially, a diode allows an electric current to flow in one direction, but bl … ocks it in the opposite direction. Thus, the diode can be thought of as an electronic version of a check valve. Circuits that require current flow in only one direction typically include one or more diodes in the circuit design.

They allow the flow of electrons in one direction only. Thus are commonly used as rectifiers to turn ac volta … ges into dc. [A dry cell (mistakenly called a battery, which is a group of cells) will allow electron flow in one direction only, or rather, it will provide current flow in one direction. ].

voltage-The term most often used (in place of electromotive force, potential, potential difference or voltage drop) to designate electrical pressure that exists between two points and is capable of producing a flow of current (when a closed circuit is connected between the two points).

ampere (amp) - Unit of measurement for the rate of electrical current flow characterized by the symbols I (in ohm's law formulas) or A. One ampere is the current flowing through one ohm of resistance at one volt potential.

Diodes. are solid state devices composed of both P type and N type material. When connected in a circuit one way, current will flow. When the diode is reversed the current will not flow.

alternating current (AC) - An electric current that reverses its direction regularly and continually. The voltage alternates its polarity and direction of current flow from negative to positive.

transformer-An electric device that changes voltage in direct proportion to currents and in inverse proportion to the ratio of the number of turns of primary and secondary windings. The input side of transformer is the primary side.
