How to Measure Inductance and other characteristics of a Coil or ...
Coils may be coreless (having an "air core" or a core made of a non-magnetic material), or they may have a core made of a magnetic material such as ferrite or iron. When measuring inductance, knowing the type of core is important because the amount of current flowing through the coil will affect the inductance of the two types differently.

How Capacitors Protect Ignition Circuits
When the points open, the magnetic field collapses, and the windings in the secondary use induction to generate thousands of volts at the spark plug''s electrodes. When the points open, the primary voltage spikes, very briefly, around 400 volts. ... This can be a capacitor or even a diode. Scoping Coils. If you have a two-wire coil, the two ...
How to Make a Coil Gun
Once the switch is open, the capacitor will discharge through the loop formed by it and the two 1M. If the left 1M was not there, there is no loop from one end of the capacitor to the other to allow the capacitor to discharge. ...

8.2: Capacitors and Capacitance
This type of capacitor cannot be connected across an alternating current source, because half of the time, ac voltage would have the wrong polarity, as an alternating current reverses its polarity (see Alternating-Current Circuts on …
Inductance of a Coil
Where: L is the inductance in Henries, V L is the voltage across the coil and di/dt is the rate of change of current in Amperes per second, A/s. Inductance, L is actually a measure of an inductors "resistance" to the change of the current flowing through the circuit and the larger is its value in Henries, the lower will be the rate of current change.
How to build a Solid State Tesla Coil | SSTC 2 by Loneoceans Labs
Construction. 2013 . Secondary and Primary Coils. Secondary Coil. In SSTCs, there are a few things to focus on when designing the secondary coil - we want to have good coupling but not too much so that arc-over (from primary to secondary or racing sparks on secondary) occurs, and we want to increase our primary inductance to reduce magnetizing current (but not too much since …
9.2: Inductance and Inductors
If the current is not changing (i.e., in steady-state), then the voltage across the inductor is zero. In this case, the inductor behaves like a short, or more accurately, like its (R_{coil}) value. In contrast, during a rapid initial current change, the inductor voltage can be large, and thus the inductor behaves like an open.
