Balanced Circuit

balanced circuit

[′bal·ənst ′sər·kət]

(electricity)

A circuit whose two sides are electrically alike and symmetrical with respect to a common reference point, usually ground.

An electric circuit that has been adjusted to neutralize the mutual induction of an adjacent circuit.

Balanced Circuit

an electrical circuit whose action is based on the geometric equilibrium (balance) of the currents (voltages) in it, or on the upsetting of that equilibrium when changes occur in a circuit parameter or in the frequency of the supply current (or supply voltage). Balanced circuits are used as electrical bridges for electrical and electronic measurements, as transducers converting one form of energy to another, and as modulators and detectors in devices of single-band radio communications, high-frequency telephone communications, and so on.

balanced circuit

A three-wire electric circuit in which the load is the same on each side of the neutral wire.
