I got a 20 amp recept circuit to trouble shoot...should I use a voltmeter or ohms law?
Figuring square feet is not algebra...it’s simple math.
L X W X H
Configuring the formula used to find the answer on the opposite of the equals symbol is algebra.
L X x X H = sq ft.
You are correct, figuring square feet isn’t algebra - but determining the number of gallons of paint needed is. And as with the other problems I posted, you not going to derive the answers with a framing square.
As far as your electical question is concerned, you’ll have to give me more information. If the problem is you think there’s no power, then to test the circuit you need a meter; if you’re trying to allocate the number of outlets you can run off of a single circuit, then Ohm’s law applies...
