I live in a mobile home. I have an issue with an outlet. Every time we plug something into it, it makes another outlet in the same room go out. If we remove whatever was plugged into the first outlet, the second one just dies out. When we plug something into the first outlet we have to play with it to get the second one to turn back on.
1) Make sure your insurance is paid up and all important document stored in your bank deposit box.
2) Since you don't understand outlets and electricity, DON'T mess with them! Somebody is likely to get hurt and/or killed.
3) Talk to an instructor at the vocational college or an electrician!
A competent electrician can fix that in a minute or two, but somebody has to pay for travel time and gas. Since it is not really worth their while to make an official house call, they might suggest somebody, who lives in walking distance, who would do it for a cake.
I'm sorry to say this, but if it means preventing a fire and losing everything, please hire an electrician. Mobile homes are notorious for electrical issues. And fires. Do what you can, please, to stay safe.
You may not have enough electrical capacity in your home. That is why when you plug something in something else goes out. Unplug something and then plug the new thing in.
Check the wiring in both outlets. Be sure to turn the power off at source! A loose wire in one or the other might be the cause of this problem. If you feel uneasy about the potential for fire, and not happy about your ability to deal with it, do call an electrician. It sounds like a relatively small job, though electricians are costly. Still, better cost and security of mind.
I would suggest, as others have, that you call an electrician. Perhaps you actually need something else done to repair this, or perhaps you have other problems. Fixing electrical problems is not something that everyone can do; it is not like making toast.
It sounds like you have too much plugged into the one outlet. Try to make it so there are about an equal number of plugs being used.
