I have been out of school for 25 years and forgot the formula for ohms law. Is it r= a over v? will be taking a test for gema plant and need all the help I can get. Thanks.

Looks pretty good for exams!!Check out http://www.technotetime.com I have one of their watches, and I use it all the time at both school and work. It can be hard to remember everything all the time, and this makes a handy dandy little reference rigth on your wrist.
my question is: are these watches OSHA approved, to wear while on the job, when you're working with electricity, or stand to be shocked being near live electrical work being done?Check out http://www.technotetime.com I have one of their watches, and I use it all the time at both school and work.

Ohms Law: R = U/IIt can be hard to remember everything all the time,

Ohms Law: R = U/I
Watts Law: P = U*I
You might have seen the two triangles:
U
-----
R x I
P
-----
U x I
They don't show up properly here of course and some will want to use E (Electromotive force) instead of U
Cover the one you want to find and the formula is revealed. Mixing the two is simple math.
Those who can't remember those two triangles without strapping trinkets on their wrists needs to go back to school
Hmm, the word "unique" means "one-of-a-kind", so if you want uniqueness, get it tattooed in a fancy way and while you're at it, get the colour codes as wellthe watch is a unique gadget/tool to say the least.

Soeren, what does the "U" stand for? (E="electromotive force", U=?) and does anybody know why "I" stands for "Current"?Søren;20382 said:.....................some will want to use E (Electromotive force) instead of U
