The cathode of Zener diode in a voltage regulator is normally,
If a certain Zener diode has a zener voltage of 3.6 V, it operates in
For a certain 12 V zener diode, a 10mA change in zener current produces a 0.1 V change in zener voltage. The zener impedence for this current range is
The datasheet for a particulat zener gives Vz=10 V at Izt=500 mA. Zz for these conditions is
A no-load condition means that
A varactor diode exhibits
An LED
Compared to a visible red LED, an infrared LED
The internal resistence of photodiode
A diode that has a negative resistence charecteristic is the
An infrared LED is optically coupled to a photodiode. When the LED is turned off, the reading on an ammeter in series with the reverse-biased photodiode will
In order for a system to function properly, the various types of circuits that make up the system must be
