It's surprisingly straight-forward. Just a case of pushing the right things into the right slots, and most motherboards come with a manual to show you what goes where. As long as you ground yourself every now and again and before touching sensitive parts, there's not much that can go wrong. :smile:
Do it like this. Consider the LED to be the laser. Depending on the ratings of your lamps, you might want to put the lamps in series, maybe even with a resistor (but keep the laser parallel to them).
Because both the neutral and the ground wire are at the same voltage, 0v, so electrons (current) have no need to flow. No shock.
The hot wire on the other hand is not at the same voltage, it is either higher or lower than the ground (changes 60 times a second). Therefore the electrons will...
The only alternating wire is the live (hot) wire. It alternates between 240v and -240v 50 times a second (50Hz) here in the UK. The neutral (non-hot) wire is effectively tied to ground (0v) which is why you won't get a shock if you hold the neutral (non-hot) and groud wires (they're both...
Hi,
I'm an A level student here in the UK, and have just handed in my rushed piece of coursework on how the incident angle of radiation effects the power produced by a solar cell.
Obviously I came to the conclusion that most was produced when the radiation was falling perpendicular but...
