Experiment Ep-02
Tesla Coil
Description: A
Tesla coil is brought into class. It has two spark gaps: one in the parallel connection,
which breaks down at 15 kV and becomes conducting, and another connected to the
secondary coil of the coil. This output provides high frequency, high voltage
power. If the frequency of the system is very high, one will have mostly corona
and few sparks, as sparks do not have sufficient time to propagate. If the frequency
is lower (500 kilocycles or less), one can develop long sparks.
Tesla
coil setup for this experiment.
In addition to showing the classic apparatus, this experiment may be used to
demonstrate the different methods for charge discharge (sparks and corona).
It is especially effective when paired with Ep-05.
Sparking
Tesla coil. Note the locations of the two sparks: one is in the parallel connection,
the other is in the circuit made with the secondary winding.
