About This Product
With the supply and meters built in, students can plot the current-voltage curve of a PN junction diode in forward and reverse bias. The readings show the knee voltage, the rapid rise of forward current and the very small reverse current. Educational Instrument can arrange export supply of the PN Junction Diode Unit to South Korea, South Africa, Indonesia, Antigua and Barbuda, Seychelles and Jamaica.
