bias current

[′bī·əs ‚kər·ənt]
(electronics)
An alternating electric current above about 40,000 hertz added to the audio current being recorded on magnetic tape to reduce distortion.
An electric current flowing through the base-emitter junction of a transistor and adjusted to set the operating point of the transistor.
