Default i need help like asap.

now iam a union apprentice electrician who has a test on the njatc theory demonstrator and i need help. my teacher is to smart for his own good and i work eight straight twelves this week and i would like to know is their a place online where i could get help or could yall draw some diagrams on how to find voltage, current, and ohms on series and parallel circuits. please i need help cause i dont want to flunk out my first years cause of this damn trainer.

Pick up a copy of "Shaum's Outlines - Basic Electricity" it does a pretty good job on the fundamentals and has test questions at the end of each chapter.

Why would it be the instructors fault that you failed to prepare for the test? I'm sure you had more than 1 week's notice for the exam. About 1/2 of the apprentices flunk out of first year. Those that take it seriously succeed, those who don't fail. Use this as a learning experience. There is a reason why we are deservedly the highest paid tradesmen. It takes study & effort both on the job & in the classroom to make it.

How do you squeeze 8 days into a week? That's the real question?
Just busting your stones.

The uglies book has the ohms law broken into any combination you may need.good luck

no not the ohms law. look we have dc theory on a trainer and you have to use a multimeter to find voltage, ohms, and current. do i have any union electricians in here who understands the question?

It's purely resistive circuits right? no inductors or capacitors? if so just remember V=IR V is constant in parallel circuits. I is constant in series circuits. From that, you should be able to solve any question

i understand that but its putting circuits together on the trainer and then using the multimeter to show the teacher that you know how to do it on the trainer. i.e. hands on. plz somebody who is with the union help me. they know what trainer im talking about.

I'm in the union and we didn't use "the trainer". Every local has a different setup. Every body here is being helpful you just aren't listening!

Whatever this trainer is all you have to do is understand and apply basic ohms law. If you don't know ohms law by now you are screwed on this test!

Go to Home Depot and pick up an Uglys book, it will serve you throughout your career and has examples of how to solve problems using ohms law.

I put together a trainer that had all the same wires (including the same colors) going into the back and out the front to switches, contactors, receptacles, lamps etc.

The whole idea was to encourage students to use test equipment to wire, trace and troubleshoot circuits without pulling on wires.

I also wrapped components into numbered boxes with leads hanging out and the students were required to identify the resistors, capacitors, diodes etc. by testing methods.

I did everything I could to help the students learn, not be a hard a$$.

Sounds like ou do understand the theory. If you do and you know the resistor color code, then you should be able to work on the trainer. You should be just confirming what you already know with your meter.

I agree with ^, you didn't study. the trainer is just a physical equivalent of series and parallel circuits. ohms law and kirchoffs law tell you how to solve the circuits. nodes add to zero for current (kirchoffs law). if you didn't study the material, shame on you. find series and parallel ckts on line or go to a book store and solve the practice examples. knowing the 2 of any 3 parameters accross a series resistance tells you the 3rd (what your voltmeter or ammeter will tell you). start studying, sounds like you are going to fail.
