also, the easiest way to resolder when i replace the part.
specifically a mosfet…..16 pins

i have opened alot of things loike gameboys phones and controllers, and all the circuit boards look exactly the same. so what is it that makes them work differently? what makes the circuit board in my phone work differently from the one in my game boy?

i know there all the resistors and transistors but how do i tell what they are and what else is on there. also can i use just an random circuit board for anything or are they made special for certain things.

A fuse is a device designed to break a circuit, usually by melting when the current exceeds a certain value. Fuses are widely used in electronic equipment, but have been replaced by circuit breakers in household wiring. In the "old days" people would sometimes replace a blown fuse with a penny, which happened to be the same size as a fuse. Was this a safe practice? Why

High-voltage power supplies are sometimes designed to have a rather large internal resistance as a safety precaution. Why is such a power supply with a large internal resistance safer than one with the same voltage, but lower internal resistance?

Can all combinations of resistors be reduced to series and parallel combinations?

Old-time Christmas tree lights had the property that, when one bulb burned out, all the lights went out. How are these lights connected, in series or in parallel? How could you rewire them to prevent all the lights from going out when one of them burned out?

I am an Electrical Engineering student. I want to design PCB. So I need any simple circuit website, so from there i will pick the circuit…

heres what it looks like:

This is a power board for a laptop. I crossed the pos. and neg. terminals and fried one or more of the components on the board. I know you can buy any component you want at mouser.com but I don’t know how to find them. Can anyone help? Here is a picture

I am looking for a simple electronic organ circuit that will let you play multiple notes at a time, I have only been able to find one online and it is only one key at a time. I am not opposed to wiring a circuit for each key if thats what it takes. Btw, I have 36 keys (3 octaves).
