reduced from a higher value to the same definite value.
LOAD ¾
The power consumed by a machine or circuit in performing its function.
POLARITY ¾
Having two opposite charges, one positive and the other negative.
VOLTAGE ¾
Electrical pressure; the force which causes current to flow through an
electrical conductor.
