inductive time constant
denoted by $ττ$, the characteristic time given by quantity L/R of a particular series RL circuit
inductor
part of an electrical circuit to provide self-inductance, which is symbolized by a coil of wire
LC circuit
circuit composed of an ac source, inductor, and capacitor
magnetic energy density
energy stored per volume in a magnetic field
mutual inductance
geometric quantity that expresses how effective two devices are at inducing emfs in one another
RLC circuit
circuit with an ac source, resistor, inductor, and capacitor all in series.
