This is solved by assuming the diodes current is zero, and solving for the current needed to raise the zener diode voltage to 3V. Now that you know what current is going to turn on the diode, is 3mA greater or less than this current? With the state of the zerer ...
Whereas in the reverse bias, it initially works like an insulator, but when the applied voltage becomes high enough to reach a special voltage called zener breakdown voltage, its conductivity suddenly becomes very high and it behaves like a very good conductor. Zener diode is made specifically to...
Step-by-Step SolutionStep 1: Definition of Zener Diode A Zener diode is a type of semiconductor diode that allows current to flow in the reverse direction when the voltage exceeds a certain value known as the Z
Line/mains voltage is too high to be connected directly to an Arduino. The ADC cannot measure voltages that high. Some sort of pre-scaler is required to...
How can I use a Zener diode to create a relatively constant voltage that is not affected significantly by changes in temperature and supply voltage?Combine a Zener diode that shows a near-zero temperature coefficient at close to 5 V with a constant-current so...

Identify Blocks Truly expansive schematics should be split into functional blocks. There might be a section for power input and voltage regulation, or a microcontroller section, or a section devoted to connectors. Try recognizing which sections are which, and following the flow of circuit from input...
How to Calculate the Emitter Current Limiting Resistor in Parallel BJTs It is actually very simple, and could be calculated using Ohm's Law: R = V/I, Where V is the supply voltage used in the circuit, and "I" could be 70% of the transistor's maximum current handling capacity. ...
Light-emitting diodes (LEDs) augment the diode symbol with a couple lines pointing away. Photodiodes, which generate energy from light (basically, tiny solar cells), flip the arrows around and point them toward the diode. Other special types of diodes, like Schottky's or zeners, have their ...
