Zener diode voltage regulator (video) | Khan Academy
A Zener diode can limit the voltage across it, making it a voltage regulator! In this video, let's explore how a Zener diode can be used to regulate voltage. We are going use it's reverse …
Diode as a circuit element (article) - Khan Academy
Diodes conduct current in one direction but not the other. We solve a diode circuit graphically by plotting a diode i-v curve and resistor to find the intersection.
Diode (video) | Semiconductor devices | Khan Academy
The numbered types identified in this video are showing a progression of diode models, starting with a very simple model, and progressing each time to something closer to the performance …
PN diode characteristics (video) | Khan Academy
we've seen in previous videos that when you forward by as a pn-junction it conducts and when you reverse bias it it doesn't conduct in this video we'll see how to summarize this entire …
Diode graphical solution (video) | Diode | Khan Academy
We solve a diode circuit graphically by plotting a diode i-v curve and resistor to find the intersection. Graphical solution methods are a common way to work with non-linear …
Voltage (video) | Getting started | Khan Academy
If a drop (Amps) of water falls from 200 metres (voltage) above You (LED, as in Light Emitting Diode), You would not get hurt (the LED would not blow). You also don't get hurt if 100 gallons …
Photodiodes - (working & why it's reverse biased) - Khan Academy
let's explore what photodiodes are how they work and where they're useful so photodiodes are a class of diodes that convert light light to electricity they convert light to electricity and they are …

What is inside a hair dryer? (2 of 2) - Khan Academy
I took apart a hair dryer, and inside is this thumb-sized black box. What does it do? It was connected to both leads of the motor by a 200-ohm resistor. I can share the circuit diagram if …
Superposition (article) | Circuit analysis | Khan Academy
Superposition is a super useful technique to add to your toolkit of circuit analysis methods. Use superposition when you have a circuit with multiple inputs or multiple power sources.
