I see PWM as a way to turn pulsed DC into a varying or alternating signal (AC). It would be clearer if I could use smoothing capacitors and show off a sinewave, but the simulator software I use cant run fast enough for it to be clear to a viewer so I went for the motor demonstration. Hope that helps

Hi, That's the current flow, in order to calculate that you need to add the bottom two resistors in parallel, Then using that new resistance and first 10K resistor youd be able to calculate the current flowing through each.

Good morning. I've watched this several times. My plan is to focus on one thing until I get it. Even in my sickened state I'm starting to get it. Does the data sheet give you the max current the diode should be exposed to so I could calculate the resistor needed to limit the current?
@electronicshandbook87882 жыл бұрын
Hi, Every diode data sheet will list something like IF ( Forward Current ), which could be a large range of values depending on the diode you're using, for example 1 amp. To be clear that is just the maximum current that can pass through the diode, you can of course pass less current if you wish. Hope that helps, Ben

Hi, Just for clarity, a 2V drop is very common but it is absolutely not always the case, there are definitely LEDs out there that I have used before that have a different drop, that's why its always worth checking the component data sheet if you're not sure.

I'm just getting into electronics as a hobby and I'm looking to learn. After searching the internet for a few weeks I have yet to find anyone who starts from scratch and has the ability to explain things without making a lot of assumptions. For instance, standard diode? What makes a diode standard? Why do you need a resistor to act as a load? This is what I've got. One of the uses of diodes are to allow voltage to only flow in one direction. There is a voltage drop, in this case 0.7 volts. The diode has a resistance that causes this? It loses the voltage as heat? I recall that an LED has a typical voltage drop of 2 volts. At least that is what I have been told and seems to hold up in my calculations. Forward current, I've heard that said several times. It seemed to be the same as voltage drop. But is it? On the chart you show, which has no values to it, am I to assume that the upward and downward trends are current flow? What would the downward suggest? Ground? See what I mean. There's at least as much left unsaid. But, I should say you have done as good a job as anyone I've seen.
@electronicshandbook87882 жыл бұрын
Hi, Im glad you're picking up a new hobby, hopefully you'll start to love electronics as much as I do. The reason we need use a resistor as a load is because you generally don't want to make a circuit without some kind of load simply because the wire itself has a very small resistance maybe 0.1 Ohms, so we don't have control over the current, that might be a bit confusing so i think the best way to understand would be to try the following LED circuit yourself: everycircuit.com/circuit/6020702572118016 In this circuit we know the LED only want about 20mA, which we control using ohms law by having a 12V source and taking off 2V for the LED voltage drop, and a 500 ohm resistor, V/R=I or 10/500=20mA Try seeing if you can make the circuit work without a load resistor, you'll notice the LED will keep blowing up, the only way you'll be able to make it work is if you set the supply to 2V which is the voltage drop of the LED. Essentially we like to try and always use a load resistor because without it you don't really have control over the current. Onto your next main question, the way a diode works is below 0.7 Ohms its resistance is extremely high, but above that value its resistance lowers very quickly, this is why we call them semi-conductors as they conduct electricity some of the time. Forward current is a measure of the maximum current you can flow through a diode when above that 0.7V, it will be different for every diode. The graph has voltage on the X axis and current on the y axis so its a graph of both current and voltage, the reason it has no values is because the graph will differ for every diode you find, some will have lower breakdown voltages for example, some will have high forward current. There are even diodes that have different voltage drops, I will be doing a video on them soon. I hope that I have been helpful, let me know if you have any questions in response, happy to help :)

I have practiced doing circuit analysis. I find math fascinating. Yesterday I soldered up my first circuit. It was a push button and an LED, running on 9 volts with a terminal block to add wires to get the 9V into the board. It worked perfectly.

What is the coupling coefficients and why does it go nuts if you adjust it from 1 to 1.01? But not if you adjust it to 2. Think originally it is set at .99 so if you hit the + sign twice you’ll see the volts either spike or drop dramatically. Do you think it’s just a glitch in the software or is that going to happen in real life? Just wondering… great videos btw , I really happy I found your channel. The way you explain things makes it super easy to understand. Keep up the good work . Thanks
@electronicshandbook87882 жыл бұрын
Hi, Coupling Coefficient in simple terms is basically a measure of transformer efficiency. If you have a coupling coefficient of 1 that means that 100% of the magnetic flux or 'power' on the primary is converted to the secondary. A coupling coefficient of 1 is impossible in real life though because there are loads of small losses and inefficiencies, however I simulated a coupling coefficient of 1 in the video as its easier to understand as a viewer who is learning. A more realistic coupling coefficient would be 0.99 or 0.98 but you will notice the output dip slightly. Thanks for the great feedback and I hope that helps!

Hi, Thanks for the great feedback, i'm glad to hear you enjoyed the content. The 10K ohm resistor is a pull-down resistor in the N-Channel circuit, or a pull-up resistor in the P-Channel Circuit. The purpose of a pull-down resistor is to help keep the transistor base pin low when the transistor should be off, and allows the small amount of current flowing from the supply to go somewhere. The pull-up resistor is the same but inverted, it helps ensure the transistor base pin is high when it should be. Pull-down/up resistors are used all over electronics and whilst not always strictly necessary, they are often recommended. I hope that helps

@electronicshandbook87882 жыл бұрын
Hi Mario, Great questions, the gate pin of a MOSFET in an ideal world draws no current at all, in practice it draws a few nanoamps. However because there is no current flowing through the 1kOhm resistor there is also no voltage drop across the resistor. This is because Ohms law teaches us that voltage is equal to current times Resistance and if there is no current and the resistance is fixed then there cannot be a voltage drop. I hope that makes sense!
