Aside from the ability to easily convert between different levels of voltage and current in AC and DC circuits, transformers also provide an extremely useful feature called isolation, which is the ability to couple one circuit to another without the use of direct wire connections. We can demonstrate an application of this effect with another SPICE … Read more
Question: Describe the basic construction and parts of a Transformer? The basic construction of transformer involves two coils of wire that are wrapped around a ferromagnetic core. The figure below shows a transformer cut in half and showing its core and windings: Note that the transformer has two windings namely: Primary windings Secondary windings And … Read more
A Coil of Wire and an AC Source Suppose we were to wrap a coil of insulated wire around a loop of ferromagnetic material and energize this coil with an AC voltage source: (Figure below (a)) As an inductor, we would expect this iron-core coil to oppose the applied voltage with its inductive reactance, limiting … Read more
So far, the filter designs we’ve concentrated on have employed either capacitors or inductors, but never both at the same time. We should know by now that combinations of L and C will tend to resonate, and this property can be exploited in designing band-pass and band-stop filter circuits. Series LC circuits give minimum impedance at resonance, while parallel … Read more
Capacitors store energy in the form of an electric field, and electrically manifest that stored energy as a potential: static voltage. Inductors store energy in the form of a magnetic field, and electrically manifest that stored energy as a kinetic motion of electrons: current. Capacitors and inductors are flip-sides of the same reactive coin, storing and releasing … Read more

The Q, quality factor, of a resonant circuit is a measure of the “goodness” or quality of a resonant circuit. A higher value for this figure of merit corresponds to a more narrow bandwith, which is desirable in many applications. More formally, Q is the ratio of power stored to power dissipated in the circuit reactance and … Read more
