Thread: Some questions - need help asap... EXAMS:(

Hello Everyone,

I need some help as soon as possible...

What are the Unit and Symbols for the following:

-Current (UNIT & SYMBOL?)
-Resistance (UNIT & SYMBOL?)
-Power (UNIT & SYMBOL?)
-Energy (UNIT & SYMBOL?)
-Voltage (UNIT & SYMBOL?)

If anyone could please help me? I have exams that are worth 30 percent of my mark on Monday.

Thankyou,

You might want to check SI. From what I remember:

Current - A, Ampere
Resistance - R, Ohm
Energy - E, Joule
Voltage V, Volt

No idea about Power, though. You mean political power?

Oh, and these kinds of questions, they are not really appropriate in a forum where people DISCUSS these matters.

Mr U

Power is the meassure of how qickly work is being done or how quickly energy is being used or converted.

Power = energy converted/time or power = voltage * current

Power is meassured in watts (W)
