To measure a zener diode’s breakdown voltage, you need a dc voltage source whose voltage exceeds that of the zener voltage. In Figure 1, resistor R SER provides voltage drop between V IN and V ZEN. In ...
Proper precision calibration resistors are expensive and usually bulky, often in a large box or can. These are overkill for low-cost handheld digital multimeters (DMMs) and LCR Meters, especially when ...
Download this article in PDF format. Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in ...

What Makes Electricity Work? It Starts with This
Electricity powers everything from your phone to your refrigerator—but have you ever wondered how it’s controlled inside a ...
To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum voltage ...
Change in life is inevitable. You know this, yet sometimes you just choose not to accept it. You just close your eyes and think the world has also stopped. But even you realize that’s not the case. It ...
