The cathode filament and the anode plate are parallel to one another. This planar configuration corresponds to the conventional symbol for a diode. A circular metal plate mounted behind the filament ensures that the electric field between the anode and cathode is uniform.\u003cbr\u003eThe diode allows basic experiments to be performed on the Edison effect (thermionic effect), demonstrates how the emission current depends on the power supplied to heat the hot cathode, allows recording diode characteristics and shows the use of the diode as a rectifier.\u003cbr\u003e\u003cbr\u003eSpecifications: ..\u003cbr\u003eFilament voltage UF:\tmax. 7.5 V AC\/DC\u003cbr\u003eAnode voltage UA:\tmax. 500 V\u003cbr\u003eAnode current IA:\t2.5 mA, approx.
