For this reason, induction coils were called spark coils. An induction coil is traditionally characterised by the length of spark it can produce; a '4 inch' (10 cm) induction coil could produce a 4 inch spark. Until the development of the cathode ray oscilloscope, this was the most reliable measurement of peak voltage of such asymmetric ...
The blue trace, i 1 is the current in the coil's primary winding. It is broken periodically by a vibrating contact in the primary circuit called an interrupter. The changes in current create a changing magnetic flux in the coil which induces a high voltage in the secondary coil, v 2 shown in red. The voltage induced in the secondary is ...
An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...
The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic assemblies. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays. Industrial electrical installations often use reference designators according to IEC 81346.

Turning the shaft rotates the coil, moving the contact wheel up or down the coil, allowing more or fewer turns of the coil into the circuit, to change the inductance. Probably the most common type of variable inductor today is one with a moveable ferrite magnetic core, which can be slid or screwed in or out of the coil.
LC circuit (left) consisting of ferrite coil and capacitor used as a tuned circuit in the receiver for a radio clock Output tuned circuit of shortwave radio transmitter LC circuits are used either for generating signals at a particular frequency, or picking out a signal at a particular frequency from a more complex signal; this function is ...
File:Induction coil waveforms.svg; File:Induction coil waveforms with capacitor.svg; Primarily, the figures do not show the effects of breakdown. The comments are misleading. The first figure has an odd idealization. Apparently it wants a stray capacitance to explain a limiting peak voltage but then ignores the capacitance for the decay.
