About This Product
With the base supply set, students raise the emitter voltage and record the emitter current to trace the UJT curve. The readings locate the peak and valley points and show the negative resistance region that suits the device to switching circuits. Enquiries from Egypt, Belize, Mongolia, Luxembourg, Seychelles and Comoros for the UJT Characteristics Apparatus receive an export quotation.
