High-frequency currents
nIndependently wealthy, in 1889 Tesla returned to his New York laboratory to pursue his interest in high-frequency currents.
nAt an AIEE meeting in
May 1891, Tesla gave his first
public lecture and demonstrations of his high-frequency work.
nHe created sheets of
flame and caused sealed tubes
of gas (Geissler tubes) to glow without a direct electrical connection to them.
