ANybody know how to work out the Voltage over a Resistor?
Elctronics querstion
Use U = IR (and P = IU).
what U and P?
i am using I x R
i am using I x R
V = IR where
V is voltage
I is current
R is resistance
P = IV where
P is power
I and V as above
Also:
P = (I^2)R
same variables as above. In case you've never seen the notation, ^ means to the power of, so (I^2) means I squared.

Yes, as far as i can remember on our physics class voltage= Current times the resistsnce. Your asking too whats a resistor.. I know its the device use. I resistance is what youre askingm the above post is right.

thats col, i cracked it, it wasnt as hard as i though ti t was, but cheers anyway shamps
That seriously was kid stuff, for people doing a levels or equivalent. U seem to be in grade 10 or somewhere near to it. N being a web geek, u should already be interested in things like this.
Well, i was, and I think many frihosters would as well be.
Warm Regards,

V=IR, it is the first equation that you will learn while start learning electronics.
I think we have an answer.
