While explaining Ohms law to someone I realised I did not understand why becomes
I know , using practical numbers but I do not know how to prove it
Thanks very much and yes! I do remember doing exponents ( 1980's)
I am OK with the explanation except where the fourth expression inverts P&R - why does that work . I am OK with the fifth , sixth and seventh expressions
How does every one put mathematical symbols in here? Math pad and cut and past ?
BTW I was in Lexington MA. last October -nice area
Thank you
I was OK with the explanation until the R &P expressions were inverted - how does that work ... using practical figure I see it does but why
Sorry for using E instead of the SI unit V but the old "ohms magic circle" I was using for my friend showed E as ( energy) for volts and I did not want to confuse him at this point
The blind leading the blind comes to mind
