Hi I have what looks to be a blown resistor in one of our blenders.
I had a look online and calculated the resistor to be 49 ohms but I am unable to find any new ones to buy.
I have attached a picture in case my calculation is wrong so please feel free to correct me.
If any other resistors will...
Well to start i am in no way an electrician or an engineer. Lol I'm just an old ironhead, im a ironworker and my hobby is electronics but I'm always working in the software side but as of lately I been dabling in the hardware side and got a soldering iron and everything needed with it I havnt...
Hi Guys I’m looking to build a circuit which will light an led when it detects an 420k resistor will i require a transistor circuit for this to work?
If this post is in the wrong section I apologise i am a new user?
Greetings. A vendor selling TP4056-based 5 V charging modules for Li-ion cells specified the following resistance values and resulting current for selecting the current-programming resistor:
I have old ATX PS and I am trying to fix it and then will convert it to bench PS.
after checking the PS, I found a broken Zener (or exploded) next to a broken resistor.
I can guess the resistor value as it is not completely damaged, but the Zener is coming our in pieces and need your...
A 20kV, 100VA generator is protected by differential protection. 70% of the winding will be protected against the phase. What is the value of resistance to be located at the "Neutral to Ground" protection if the relay operates 30% out of the balance current?
Below are my steps to the solution...
Iam still pretty new to electronics this is my first time using a RGB led i plan on each color to be on at one time no mixing colors, the part iam using is a common Anode RGB I planned on using a 5v power source to connect my anode to, the max led ma each color can handle is 20ma which i...
I have built this motor circuit for my Arduino and when running it only gets less 1v and the motor spins very slowly and my bigger motor doesn't spin at all. I have attached the diagram that I followed below. The Motor should be getting 5v from the Arduino although something seems to be...
Hi guys, this is my first post here. I hope I'm in the right section.
I've made a slayer exciter with a 22kohm resistor, a 2n2222 transistor, using a 9v battery. My secondary is 0.25 mm and 10 cm in lenght. My primary is 4 turns.
I wanted to obtain some sparks, and I added a 47k instead of 22k...
I’m pretty much a noob when it comes to hardware and for awhile I have been trying to figure out how to design a PCB layout. The Problem I have is trying to figure out the values for capacitors and resistors how to connect them with the other parts (like pull up resistor, bypass capacitor etc...
