I have a test to study for that deals with electricity and I have no clue how to do any of it. For example I have a question on here that says what is the total current of the circuit ? There is a picture of square one the left side of the square it has 150v on the top it has 14k and on the bottom right side it has 48k and the answer is 3.0mA how do they get that answer and the k that is behind the 14 and 48 what does the k's stand for ? And what does Ω means ?

If you have completely no idea how to do any of this why are you being tested on it? Doesn't seem logical.
Just curious.

It's a test that a job is asking for to basically see where you at how much do you know its other parts to the test I have samples of the test the other parts of the test are easy stuff that I already did and know but I never dealt with motor electricity dealing with currents, circuits, logic traps resistants, ohms and so forth and there are a couple questions on the test about that type of stuff.

So why not be honest and say you are not experienced with any of it?
What if you fake your way through and have to deal with all that on your daily job?

I have worked in education on and off for 45 years. The best test will have questions you can answer and ones you can't. They are looking for strengths and weakness (we all have both) so you should answer what you can and not worry about the ones you do not know.
