Where to start... Ok well I'm not the brightest of people and did not have the best education as a child, but I'm trying to improve myself so please forgive me because I will be asking some really easy questions (well to almost all of you guys anyway) but I have to learn somewhere so I would appreciate any help you are willing to give, many thanks in advance.

So to start with I would like to learn how I go about working this out;

P=EI=(IR)I=I2R (sorry don't know how to make the 2 small)

I understand that P is power which is = to E times I (E being Voltage and I being current) but then the part in brackets, am I right in saying this is I times R (resistance) and if so what do I do with the I after the brackets to get the right answer to a question?

As I said this will be basic to all of you, but even so I would like your help if you wouldn't mind

Many thanks

Tom
