Main Question or Discussion Point

Hi all

Need some help on transposing formula's.

I know i've tranposed before, but was years ago.

Returning to college etc,
the formula is

e=Blv

whats confusing me is there are 3 values being multiplied by themselves, all my previous formula's have been V=IR ect, those I find easy.

How would I make "l" the subject

I know to make "v" the subject I would just divide both sides by Bl then cancel etc.

Thanks

Why don't you apply the same strategy to solve for "I" or - in your terminology - to make "I" the subject....divide both sides by B v and then cancel ..

to IanNe5 in post #1, do you understand "factor" and "product"? Then, also do you understand "reciprocal"?
