I know there are windows which act as solar panels, but they're made in a different way than traditional silicon-cell solar panels, and they're much less efficient.

Assuming the sun had gone down and the device's only source of power was the LED, I would think that it would gradually lose energy. Some of the radiant energy would become thermal(however small an amount) and it would eventually go out. Now, running on a full charge from the sun and then...

Depends on the University. I live in Ontario, Canada and all of the programs I've seen require English, Physics, Chemistry, Advanced Functions and Calculus/Vectors. I'm not sure where you live, but I'm sure there would be equivalent courses. But in general, it is an Engineering program, so...

Will do! I wear Rubber Gloves anytime I'm doing anything with the capacitors. It's clumsy, but it works. I just recoiled the tube with the new wire and hooked 1.5V and 9V batteries to it and it is creating an electromagnet, so now it's just a matter of resoldering all of the capacitors...

I discovered that my wire does not conduct electricity at all. I have no idea why, but I tried different wires hooked up to a motor and it ran, but the wire I used for the capacitors and coil didn't. So I'm trying out household wire, because I have tons and it worked. Plus it's already insulated.

I have 2 camera circuits. I tried them both with the 1.5V first, and eventually sacrificed one for science. It popped as soon as I connected the 12V, but I still have 1 good one.

Hello, I am a Grade 11 student and for a Physics project I am constructing a Coilgun. I've done quite a bit of research into actually building the Coilgun, but when it came time to charge it, it refuses to charge. I've used, 1.5V, 9V, a 12V Car Battery, and none of them will charge the...

You're replacing an Oxygen atom with a Sulfur atom. The original compound is Sodium Sulfate, which is Na2SO4, but when it becomes Sodium Thiosulfate, one of the Oxygen atoms is replaced with a Sulfur atom. So it becomes N2S2O3. If it were to be Sodium Dithiosulfate, you would replace 2 Oxygen...

Not sure if this is the place for this thread and after looking through 5 pages of a search, I didn't find a similar topic, but please tell me if I'm wrong. As you can tell I'm new, so hello, I'll probably be on here more in a few months as I'll be starting grade 11 and may need help...
