So I want to build a perpetual motion machine but engineering is such a tough feild to do, but do I need engineering to build what I want to build. I fear I might not like a life of complex math and physics. I like cars though, Ive seen mechanics build things from the ground up. so three questions.

1. Is the life of a mechanic less difficult or more difficult than the life of a engineer?

2. Does a mechanic have the skills needed to build a perpetual motion machine? "my guees is probaly not"

3. Do I need engineering to build what I want to build?

I'm not too smart when it comes to electric know how so maybe someone out there can help me out.

My breaker never tripped until I got an electric heater. I ran that thing for a few hours and while my computer on the same outlit went to sleep. Then I woke my computer up to use...pop... there went the lights.

The breaker has a 10 and it is powering my whole office. I guess that means this breaker is for 10 amps max?

The electrical heater is pulling 12.5 amps per the specs using 1500 watts on the heater so I guess thats why it's popping???
Too many amps???

Do I get an electrician to take out the 10 amp breaker and put in a 15 or 20 amp instead???

I just had a semi large fire on my deck, and I wasn't sure if I should use water at first, since the fire was on an electrical output, but not from electricity originally. I finally did, and it wasn't. But in the future, I was wondering if an electrical fire LOOKS or ACTS differently than a regular fire (as in lighting a match on paper).

I'm trying to get a DIP IC off of a PCB, but I can't get the solder to drip away from the joints. Is there any way I can keep it liquid long enough for it to drip away?

what i mean is if you have an ac current and you convert it to a dc current (or converting a dc current to an ac current) will the voltage and amperage stay the same
if not how can you predict what the drop of the units will be
