An electronic component that is used to vary, or control, the amount of current that flows through an electronic circuit.
A potentiometer is also referred to as a pot.
- power brick
(pow´&r brik) (n.) Also referred to as a transformer, an element of the external power supply for a notebook and/or laptop computer, used in conjunction with a battery pack. Since notebook computers rely on low-voltage DC, they need a way to convert the AC from a power source into DC that can be safely used […]
- power conditioner
Also called a line conditioner, a device that sits between a computer and its power supply, typically a wall outlet. The power conditioner provides protection against surges in power just as a surge protector does, but a power conditioner also maintains a continuous voltage fed to the computer during temporary voltage reductions, such as a […]
- power cycling
(1) In the case of a frozen or hung device, power cycling refers to turning the device’s power off and then on in order to get the device to function again. For example, if a desktop computer freezes, the user is unable to perform a routine shutdown by utilizing the shut down window. In order […]
- power down
To turn a machine off.
- power factor correction
Power factor correction (PFC) is a newer technology used in computer power supplies. PFC is applied to the circuits that include induction motors as a means of reducing the inductive component of the current and thereby reduce the losses in the supply. PFC has no effect on the operation of the motor itself. [Source: Adapted […]
