You did not really explain why they are used. The question is why would a 9 volt battery be used in the first place? Why not use a 1.5v battery or a power supply that fits the LED needs in the first place? How much electricity is wasted using a resistor? The answer should have started with something like it is to expensive to provide each electronic circuit with the exact voltage needed so we take one standard power supply and reduce the voltage down to the different circuits needs.(something like that.) Sorry to complain, I do really appreciate your work on these videos.

A LED needs at least 2 V to light up. So you need a bigger battery than 1.5 V.

I recently learned that a combination of capacitors, induction coils and resistors can limit the frequency that the cables allow through. I did not understand exactly how the process works, so if you could make a video explaining why it happens and how it can be used, that would be awesome!

Capacitors act like short circuits for high frequency and like open circuit or resistance for low frequencies (as you can confirm from the formula X=1/2pi*f*C) so it might be considered as a high pass filter

High School Math The resistor's current I in amps (A) is equal to the resistor's voltage V in volts (V) divided by the resistance R in ohms (Ω): I = V/R edit: Called Ohm’s Law In the video he uses a 9 Volt battery in the circuit V = 9V and a 450 Ohm resistor R = 450Ω. I = V/R = 9V/450Ω = 0.02A
@call_me_mado59872 жыл бұрын
Ohm's law states that Current=Voltage/Resistance In this case he needs the LED to only have 20mA of current and there was a 9V battery so you just do 0.02A=9V/Resistance so resistance (R) =9V/0.02A which is 450Ω Basically the resistor acts like kind of like a valve for the current to flow, so the resistor is used to limit the current so it doesn't cook the electrical components.

I am a little bit confused. Isnt the LED-example wrong in regards of the current? Usually you have a Voltagedrop of about 2V (depending on the type) on the LED. So the Voltage at the resistor is about 7V and thus the currents arent the one shown in the video. Or am i missing something?

Resistors waste energy. Is there a way to build things without using resistors?
@trollmcclure1884 Жыл бұрын
How can you limit the current from the grid to a tiny LED bulb then? Common sense tells me that there's very high current able to heat the whole house and couple of tiny resistors should just evaporate. Even a car battery can generate 100A easily. What's going on? IMO the right explanation would be that not all current over a certain value is transformed into heat. It's not clear from the video. Electrons dont lose energy and come less energetic on the other side. There's just less of them able to make it through at one time. The vid is not cooked properly. There has to be much more to tell about resistance
