Please explain my meter to me.

Bernd:
Thanks for adding that Joe. I'd completley forgotten about the rest of the hydraulic anlogy.

Bernd

ieezitin:
Gentlemen.

Thank you for helping me understand.

Bluechip, thank you. I did google and try to get some idea and it only worked so far, experience from people who know is ten times better, plus I had questions that needed to be answered. every time I got explanations when I researched it they were written as if I knew the basics of components. :doh:

Tinkerer, Bernd. Great explanations which made sense to me I now have a better basic understanding of what I am dealing with and I will experiment with parts from old trash electronics I have laying around and I will be safe.

One more time thank you all. Anthony.

Bernd:
Just thought of the other hydraulic anology. Voltage = Volume and Current = Pressure. :smart:

If I'm wrong I'm sure somebody will let me know. :wack:

I think it's the opposite.

spuddevans:
Here's another analogy, imagine a road with cars on it travelling at a speed. The road is the wire, the amount of cars = Currant and the speed of the cars = voltage.

A single lane road could allow a lesser amount of cars on it at some very high speeds, but a 6-lane highway will allow many many more cars to travel at both low and high speeds. In electronics, a reletively thin wire can carry some very high voltages (high speed cars) but only at lower currants (amount of cars), whereas a thicker cable will carry much heavier currants at both lower and higher voltages.

This is why the cables in your car are thicker than those in your home electrics, the car works on a reletively low voltage (12-14 volts) compared to the house that (in the uk) runs on 230Volt (or 110 volts in the US). So to power the same 100 watts, the car cable will have to handle around 8.3 Amps compared to the house cable will carry only 0.43 Amp ( in the uk, 0.9 Amp in the US ), raise the power to 1000 Watts and the cable size differences get even more obvious.
