AC-AC transformer What It Does,How It Works,Variants,Values,How to Use it,What Can Go Wrong

What It Does A transformer requires an input of alternating current (AC). It transforms the input voltage to one or more output voltages that can be higher or lower. Transformers range in size from tiny impedance- matching units in audio equipment such as mi­crophones, to multi-ton behemoths that supply high voltage through the national power […]

inductor What It Does,How It Works,Variants,Values,How to Use it,What Can Go Wrong

The term inductor is used here to describe a coil that has the purpose of creating self- inductance in an electronic circuit, often while passing alternating current in combination with resistors and/or capacitors. A choke is a form of inductor. By comparison, the elec­tromagnet entry in this encyclopedia describes a coil containing a center component […]

variable capacitor What It Does,How It Works,Variants,Values,How to Use it,What Can Go Wrong

Formerly known (primarily in the United Kingdom) as a variable condenser. The term is now obsolete. What It Does A variable capacitor allows adjustment of capac­itance in much the same way that a potentiom­eter allows adjustment of resistance. Large variable capacitors were developed pri­marily to tune radio receivers, in which they were known as tuning […]

capacitor What It Does,How It Works,Variants,Values,How to Use it,What Can Go Wrong

Quite often referred to as a cap. Formerly known (primarily in the United Kingdom) as a condenser, but that term has become obsolete. What It Does A capacitor connected across a DC power source will accumulate a charge, which then persists af­ter the source is disconnected. In this way, the capacitor stores (and can then […]
