capacitor

Hey guys! First time posting here! I have an Alienware 17 R3 laptop that I picked up broken to see if it was repairable (I like learning new skills). All signs point to a short on the motherboard, I plugged in the charger and the blue LED on the charger cable goes out immediately if I attempt to...

In another thread, I learned about the "Outside Foil" designation on one lead of some vintage foil capacitors. How was this connection specified on schematics or other documentation? Here is an example of the indication.

What is the purpose of that capacitor there?

Confused on choosing the correct replacement electrolytic capacitor. For example, on an Atari AR I board (built in the early 1980s), the parts list calls for two (2) 3300 uf Aluminum Electrolytic Fixed Axial-Lead 35V. The original capacitor PHYSICAL size are relatively large. When you go on...

Hi! I've only soldered a few circuits before. Tomorrow I am planning on building a mono audio amplifier with a LM386 IC. I've a thread about it here (including a link to the schematic I am working from) https://forum.allaboutcircuits.com/threads/166673 The schematic uses a 9V battery, but I'd...

Hello, While looking at some basic capacitor information I ran into a concept I hadn't really thought about before, self-capacitance. While perusing the article section on wiki I began to wonder if the material type would have an effect on the self-capacitance of a material. Essentially, my...

I’m renovating a very solid very old grindstone. I have broken the centrifugal switch that switches from starting winding to running. Before I attempt micro surgery could I bypass this method and use a capacitor instead? If so how to wire it ? it needs greater brains than I possess to figure...

Hi, So I've got this rotary floor sander I've got to fix. When I opened it I noticed someone had fixed it before and 1 of the capacitors had swollen. I've been told it had been working for a long time before the capacitor broke. I assumed the silver one was the run capacitor and the blue broken...
