Passive components
The passive components used in electronic circuits all make use of one or more of the three fundamental phenomena of resistance, capacitance and inductance. Some components depend for their operation on the interaction between one of these electrical properties and a mechanical property, e.g. crystals used as frequency standards, piezo-electric sounders, etc. The following sections look at components particularly in the light of their suitability for use at RFs, and at how they can be inter-connected for various purposes.
Resistance and resistors
Some substances conduct electricity well; these substances are called conductors. Others called insulators, such as glass, polystyrene, wax, PTFE, etc., do not, in practical terms, ...
