Electricity is ****ing magic.
Seriously, that's all you need to know. My buddy works in energized services where they honest to god replace power lines that are still hot. The guy knows his shit backwards and forwards when it comes to electricity. He has a patent or two on some shit designed to keep strikes from coming from the earth at an aura or some weird shit like that. And as we're wiring something up in my shop and talking about a jumper of some sort, I just got frustrated because I get lost as hell in that stuff. He just looks over and says "man, I'm not trained in engineering but the guys that I work with that are all tell me the same thing when my eyes cross - electricity is ****ing magic and sometimes that's the best answer we have"... So that's what I go with. I can occasionally operate a multi-meter correctly. I sometimes remember the difference between volts and amps (though I don't believe today is that day...is amps volume and volts velocity? Shit, I don't know). Mostly I just electrocute myself a lot. Electricity is ****ing magic. |

This is what he is talking about and there is a decent description at the link.

Ohms = Resistance (how difficult it is for electrons to travel through the material) Volts = Current * Resistance (also called potential difference) Does that help? |

If I understand correctly he's wanting it to shut off at about bed time & come back on about the time someone would wake up to simulate someone being home. Not sure the dusk to dawn light is going to accomplish that. |

Criminals are idiots, but they know about timers. The only thing that's going to deter them (if it will) is having the light on period. |

Amps = amount of water flowing through the hose Ohms = Pressure of thumb on the end of the hose Volts = resulting spray Run a ton of water through a hose but don't put your thumb on the end, it just runs out to no real issue. Put your thumb hard on the end with no water behind it and again, not much of anything. Put a ton of water through the hose and then put your thumb on the end of it, suddenly getting blasted in the eyes is gonna hurt. I have a basic handle on it....sometimes....but the I get the terminology turned around because I just never use it. I zapped the hell out of myself with my Sous Vide machine over Christmas because some stray voltage made it into the water bath. I put my hand in there to check the temp and got quite a jolt. It didn't hurt as much as it made it tense up quite a bit; high current, low volt? That's my memory of how that works. But again, it's all magic and like Baby Lee - I had legos and shit as a kid; the little electricity kits just didn't appeal to me. I'll build cabinets (poorly) and work on suspensions or the like (again, poorly), but I'll be damned if I'll ever get electricity figured out. |

but high current can be quite dangerous too though |

Can you link what you're taking about, the actual product?
