This was really helpful :)

One question though: I've also heard that DC has a power and a ground. Is that just the positive and the negative shown in this video? power being "+" and ground being "-"?

Thanks

[jfalbo]

Yes that is correct. Glad I helped

[Retta Quintero]

Very clear. Only one concern. My question is when you said to calculate watts you use PIE to remember the formula. But then on the chart it was EI not IE as pie would lead to an equation to p= i * e (pie) which is not as the same as the chart EI leading to an equation of p= e*i (pei)

Should i be concerned about the difference? or should i just remember pie then flip the i & e in the end.

Thanks, Great vid

[jfalbo]

I * E is the same as E * I

[jfalbo]
