About This Product
Because the circuit is built with patch cords, students practise turning a circuit diagram into real connections before taking readings. With both silicon and germanium diodes on board they can compare the potential barriers, about 0.7V and 0.3V, and work out the dynamic resistance from the curve. Schools, colleges and institutes in Portugal, Bangladesh, Bhutan, Suriname, Nicaragua and Somalia can order the PN Junction Diode Characteristics Apparatus – Socket Type from Educational Instrument.
Frequently Asked Questions
Which diodes does the apparatus include?
