Rhumkorff commutator allows primary current to be both reversed and switched ON/OFF with make-and-break point.A pair of pointed electrodes is supplied with the instrument, the pointed electrodes having an insulating handle for adjustment of the spark gap. Low voltage input is via a pair of baseboard mounted colour coded 4mm sockets.
DESCRIPTION
Useful for the demonstration of characteristics associated with high voltage phenomena such as with Geissler tubes, spectrum analysis tubes etc. This traditional induction coil is capable of producing a spark length of up to 30mm with an input of 6-8V DC and is therefore ideal for use with vacuum tubes, eudiometers, etc. A fully adjustable trembler system is incorporated and spark suppression capacitors are housed in the base Rhumkorff commutator allows primary current to be both reversed and switched ON/OFF with make-and-break point. A pair of pointed electrodes is supplied with the instrument, the pointed electrodes having an insulating handle for adjustment of the spark gap. Low voltage input is provided via a pair of baseboard mounted colour coded 4mm sockets
