1N5243B Zener Diode 13V .5W (5 pack)

in this video we're gonna focus on power Zener diodes as a voltage regulators because not all Zener diodes are the same some are more effective than others at regulating the voltage so what we're gonna do in this video is we're gonna see the relationship between the output voltage across the Zener diode with the current flowing through it the variations in the power source so we're gonna see how the voltage of the battery affects the output voltage across the Zener diode and also how it changes based on the load resistance of the output circuit so we're going to consider all of that now let's say if we have an 18 volt battery the output voltage across the Zener diode is designed to remain at 12 volts if we increase it to 36 volts the output will still be approximately 12 volts and so that's how the Zener diode works as a voltage regulator it doesn't matter what the voltage of the batter
