Not a disappearing post of mine but I was sure I saw a brief post from another member, perhaps the same member deleted their post after a rethink, perhaps my mind playing tricks, not an issue.

The part that confused me is in one paragraph 1 amp peak to peak must mean 0.5 to -0.5 Amps so they use 2 x 0.5 and in another paragraph 1 amp (p-p) means 1. I am reading the article as V = L x 2 x 1 over time when it is L x (2 x i ) over time.
