Re: Batteries and beating dead horses

[Guest guest]

Hi ,

Well it takse voltage to make the amps flow. And the more the resistance the

more volts it takse to make the amps flow.

THink of a good analogy. Compare it to water in a hose.

Water pressure is volts

Water flow as in gallons per minute is amps

If you have a small hose(higher resistance) and high pressure(voltage) then you

can get a certain flow(amps)

Makeu the hose bigger(reduce the resistance) and the amps increse even if the

voltage(wotre pressure) stays the same.

Now when it comes to the human body and your skin it has a certain resistance,

so it require a minumum of pressure(voltage) to cause enough current(water flow)

to flow.

So even though the 4 9 volt batterise is series donet have any moret amps than

one does. they do have higher pressure so they can make more of those amps flow.

Thas also th esame thnig with wire even thougch a 9 volt mbattery can fry wire

o zero resistance does nto mean it will be able to put that many amps through

the human body because the resisnatnce fo the body is much higher than a piece

of wire or a fuse. The body has a bulit in limit resistor called the skin.

Take care,

Hi V,

What I was also trying to point out is that according to Radio Shacks site, the

max voltage for that OP AMP was supply of 18 and input of 15 volts......but the

schematic on this group shows 27 volts. While I realize that there's a certain

fudge factor to voltages I just wanted clarification. Thanks

I've also used the substitutes for the LM358, as my electronics

source said they did not carry that one, being an older chip, and

found they all work with 4 batteries, too.
