Branch
In a parallel circuit, each current path is a Branch.
Band-Pass Filter
A resonant circuit that is tuned to pass a single band of frequencies and to attenuate all other signals.
Band-Rejection Filter
A network that attenuates a single band of frequencies and allows those on either side to pass; sometimes called band-stop filter.
Balanced System
A set of phasor currents (or phasor voltages) that have equal magnitudes and are separated from each other by equal phase angles.
Blocked-rotor test
A test applied to an induction motor, in which the rotor is blocked so it cannot rotate.
Bundled conductors
An assembly of two or more than two conductors utilized as a single conductor ONLY and applying spacers in order to sustain a preset configuration.
Bus
A solid conductor, or metallic strip, that serves as a common connection for two or more circuits. Generally, currents from incoming feeders accumulate on it and then further distribute to the outgoing feeders.
Bus admittance matrix
A matrix whose elements have the dimension of admittance and, when multiplied by the vector of bus voltages, gives the vector of bus currents.
Battery
A voltage source that uses chemical energy to create electrical energy.
