The simple Diode and LED Tester presented here costs under £5 to build (including all components, the battery and a cheap case) and will indicate the polarity of almost all types of LED and other ...

Figure 3 Two LED drivers operating in series or parallel let you boost zener voltage or current. Figure 4 shows an assembled zener-diode-tester circuit. The zener diode under test is On Semiconductor ...

Learn how to use a Zener diode, a series resistor, and a load resistor to create a stable and precise output voltage from a power supply, using basic formulas and components.

In production, this may be replaced with a zero Ohm resistor. The open circuit protection circuit shown utilizes R9, causing it to serve an additional function, in conjunction with Zener diode D2. In ...

Abstract: A new limiter circuit for use with electronic analogue computers has been developed from the basic diode bridge circuit. This limiter is simple in construction, has only one adjustment and ...

This paper proposes a new current balancing method for alternating current (AC) - light emitting diodes (LED). The proposed method uses the bi-directional current mirror circuit with negative feedback ...
