You need another given variable for the sequence resulting in 1. Only thing that is giving is 2a since it stays the same in a series circuit, no other variable can be found unless another given is listed. You can't find r1, e1, or p1 with just 2a.
Because you know eq 2 and 3 and part of eq total you can figure out the missing information easily. Without the other info you would be lost because you really need 2 parts of the equation to get the third part.
It would be a lot easier if this was written out as a schematic. I hate word problems.
If you don't know how electrons flow or how they react under certain conditions then how will you have any practical field knowledge?
Depending on your line of electrical work will determine if you will be calculating basic formulas, do I ever do calcs on finding Rt on a residential application ? No I do not, but when I am modifying honda computers for turbocharging and n20 applications then yes. :laughing:
I know I do, quite handy for some quick trig on funky bends too.
Onece you practice ohm's law enough (google it for practice problems) and understand it you will look back and feel really stupid...yet at first I could see it being rather daunting.
Right now we're also learning about forced air heat. Gas, electric, and oil fired furnaces. Next semester I believe is air conditioning. After that we get into refrigeration and appliances. Which I'm personally very excited about. I'm looking hard at buying into a Mr. Appliance franchise. I'd also like to own a Aire Serve as well. I know the guy that bought Mr. Rooter is dominating the market down here right now. The guy that bought Aire Serve in Spokane supposedly put six big HVAC cntractors under his first year in business.
I see good things if I do well in this course and get my degree.
