I have misplaced the capacitor that comes in the kit.

Professor Smith,
I seem to have misplaced the capacitor that came in the set. I bought a backup from RadioShack to complete the Module 3 experiments. However, I am finding that the experiment is not going as it should and I think this is because of the cap value (1000 uF). What value is the cap that comes in the set? I figure the longer the time constant the better to make the bulb light, so I will go with this thinking to buy a couple new caps that hopefully work in the experiment so I can get everything done by the Monday deadline.

I assume you rented the capacitor and generator from the bookstore.
In any case you need a 1-Farad capacitor, and you should only use the capacitor that comes with that package. A 1-Farad electrolytic capacitor can be very dangerous. It would also have the potential to melt your circuits.
You can order a 1-Farad capacitor from Arbor Scientific or another vendor (I think I've seen them on Amazon). The Arbor link is

If you need an extra week, which is what it might take you to get the capcitor, I'll allow that.
The Arbor price, indicentally, is $25.
