your remark in regards to ohms law 480 sparky. I could pass all math calculations but at the time of the test i get a little nervous. And this is that stupid mistake.!!!!

tacomafc:

Were you given one of these Greek letters and asked for the name of the symbol (letter)?

Φφ Phi
Ψψ Psi

When taking tests you should try to cross check your answer with some simple alternative means to obtain an approximation.

For example on your ohm's law problem --- If you raise the voltage on an invariant resistor what happens to the current? Disregarding any equations this should be intuitive to you. Of course the current increases. In your question you had a resistance that you had to calculate. After calculating the resistance you chose to divide the resistance by the voltage. When you do this what happens to the current? It goes down. This is contrary to what you know intuitively.

We have a person of Greek heritage in our office. He tells me this:
The Greek word for ?phase? would be ?fasma.?
The Greek words for ?single phase? would be ?mono fasiko.?
The Greek words for ?three phase? would be ?tri fasiko.?

My guess is that the author of this test question was trying (with, as it turns out, no success whatsoever) to be clever. My guess is that that person thought that the Greek word for ?phase? is, indeed, ?phase.? Do you recall if that was even one of the choices?

The questioner probably meant to ask for the Greek symbol for phase angle. Theta is commonly used here as is Phi. Capital Omega is used for resistance, Rho is used for resistivity, lower case Omega is used for radian frequency, etc.
