Why did they change E to V but left I and R.
Should it be V = A x O
Volts, Amps and Ohms.

I grew up as a kid / teenager in the 60's ... more like older generation.
As for your question regarding the above .... I was taught that V is Voltage / I is Amps and R is resistance.
Your equation above is valid ... the ' letters ' have just been changed ... why, I don't know.... in fact I didn't know they had.
I asked my daughter this question .... what is 2 1/2 % of $40.00 .... she couldn't tell me by working it out in her head....I have seen ' checkout ' staff unable to count back your change.
BTW.... the answer is $1.00 ( 10% of $40 is 4 / 5% of $4 is 2 / 2.5 % of $2 is $1 .... easy
What's happening in our schools today ... ?
