I need a little clarity for something I'm working on. If someone can validate my understanding and answer a few related questions it would be greatly appreciated. I may even name a character after you.

Via my web research:
I understand that an EMP would essentially overload electrical systems and render those systems and anything attached to them useless. I also understand that devices reliant on battery power that is not attached to a power source that is connected to an electrical grid, those batteries would still function until they ran out of power. True?

If a car is moving when an EMP occurred, would it continue to drive until the battery ran out or would the alternator be fried and the car would slow to a stop?

Solar power? Is solar power collection interrupted? Are the power storage batteries in solar systems instantly effected?

A Tesla coil? Would a fully functional large scale Tesla coil be impacted by an EMP burst?


I know I'm asking a wide range of questions, I'm trying to gain a fuller understanding of the subject before I write about it.

As always, thanks in advance
