Voltage and current phase shifting/Current without voltage?

I envy you!..

Yes. A nice way in for Jim. I wonder how many of his cohort did as well as him. I'll make him blush by saying he is a bit special where E Engineers are concerned.

Gosh, Sophie - THANK YOU SIR !

I do admire (and envy) those like you for whom math seems so natuaral and are at home with it.
I always struggled with it.

You overrate my ability. With me, it's not like that. I am pretty rubbish at Maths because I was never bothered enough to learn enough of 'the rules' that you need when actually trying to work things out. It's more a matter of 'faith' that I could if I was bothered to - or at least that "it can be shown that" by someone smarter than me. I did work with a lot of people who could cope with higher levels of Maths than I could and I really believe it's a valid way through. That's just like using an electronic device with an in and an out and some control knobs. Your employer paid £10k for it so we all believe it and it checks out against other stuff that also cost a lot. Then you look at the system as a whole and wave yer arms about a bit for a result.

Amen.
Laplace transform is beyond my comprehension.
It's quite a handy tool, though.
I suppose one doesn't have to understand equations for impulse and momentum to apply a hammer to a nail .
