- The voltage developed in an inductive circuit through which AC flows. The polarity of this voltage is at all times the opposite of that of the applied voltage. Also known as back electromotive force, back voltage, or counter electromotive force.
- A voltage whose polarity is at all times the opposite of another voltage.
- For an electrical or electronic component or device, the voltage in the direction in which there is the greater resistance to the flow of current. Also called inverse voltage (1).
