About This Product
Students increase the bias in small steps to locate the knee voltage and the Zener breakdown point, reading voltage and current directly from the displays. Adding the load resistors shows how the diode holds the output steady as a simple voltage regulator in electronics practicals. Schools, colleges and institutes in Indonesia, Zimbabwe, Antigua and Barbuda, Burkina Faso, Ecuador and United Arab Emirates can order the Digital Zener Diode Apparatus from Educational Instrument.
Frequently Asked Questions
Can the apparatus show the Zener diode working as a regulator?
Yes. Integrated load resistors let students test the Zener diode as a voltage regulator.
