Balanced Circuit
balanced circuit
[′bal·ənst ′sər·kət]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.
