I have a specification calling for a .01 microfarad capacitor, and my little ceramic disk capacitors are rated in picofarads such as 1 picofarad, 10 picofarads, etc... Which one do I use?

My circuit (a 555 timer) isn't working and I'm using a 1 picofarad capacitor where is calls for a .01 microfarad, is this correct? I'm just getting somewhat confused.

Thanks!

There are various kinds of batteries and I need to know whether any is more susceptible to an EMP than the others or if any battery not in a circuit or not grounded would be damaged at all. If damage is possible or probable, I'd like to know the kind and extent of the damage to expect. I making an assumption that car batteries still on the shelf and with no chemicals added yet would be undamaged. But I don't know. I'm assuming also that ungrounded large batteries in major installations might be safe and that smaller ones would such as flashlight batteries would probably be damaged. But, I don't know and would much appreciate good thoughtful comments.
