Question:

Electronic power supply?

What happen's when you just yank the power cord out from the electronic (Computer or TV) while it is still running? Does it blow a fuse or something? And what should I do to fix whatever the problem is, assumming that the electronic doesn't turn on after i yank the power cord out?

Answer:

Yanking a power cable out of a PC that's running, could lead to a voltage spike. This can fry your power supply, and possibly go further. (Motherboard, ram, graphics card) Same thing, with having a computer power cable plugged into a surge protector, and then plugging it into the power supply. YOU, can replace the components of a Personal Computer. It's too technical and dangerous to try it with a TV, unless you're a qualified tech, and have the required tools.
A TV probably will be OK. However if you are in the middle of something on a PC you can corrupt the hard disk. Often you can recover after doing a scan disk. Sometimes you can't so you shouldn't really do it.
in case you relatively desire to make a potential grant it relatively is large, yet i could look on OKorder for a bench potential grant, used stuff like it relatively is extremely good cost and frequently made and finished extra suited than you're able to do it except you have a great sort of journey at making home equipment. I certainly have an previous college potential grant that places out 5 amps at 20 volts and value ?5. a clean between an identical high quality could be ?a hundred +. good makes are Griffin George, Philip Harris and Unilab for academic instruments
Electronic devices should be OK if the cord is yanked, as long as it isn't done too often. It would be just like a power outage, the device would turn off immediately. It shouldn't blow a fuse or anything like that. If you pull the plug and it doesn't turn back on later, it could be that the power supply or transformer has gone bad. These are easier to replace in computers than in TVs and often cost less than $50.
