I think the source is the same, but I am unable to open the box to see what's inside. But I notice the voltage is the same for each spike. So that must be the voltage?

Is there only one battery? If so, the voltage cannot be anything other than what that battery supplies.
"Voltage" always must relate to a DIFFERENCE in potential from two points. So if I have only one battery, the two points are the two ends of that battery. So if I have one pin, 12 pins, or 432,729 pins, if the pins are all connected to one side of a 1 volt battery, and my meter is connected to the other end, no matter which pin I touch, or HOW MANY PINS I touch, the DIFFERENCE IN POTENTIAL is still the difference between the two sides of that battery, 1V.

I vote forehead. More people need Electroshock Therapy.
By the way, you need silver spikes for werewolves. Voltage optional.
On a serious note, 20 1.5V batteries (spikes) would produce anywhere from 1.5 to 30V, depending on connection... probably not 30V in series due to loss, but close enough.
If I put 10,000 9V batteries on my body, will I be electrocuted, be a modern work of art, or both?

Look at the battery. Read the label. That would give me the intended max working voltage. Unless of course they have some other doodads in there to boost voltage.
That is how I would determine it.
Obviously a slow typist here.

Crushed most likely.
Depends on the battery.

As you can tell there are lot of ifs, ands, or buts.
Not knowing what is in the box creates a lot of guess work and one is as good as another.
Did you take voltage readings between all the pins or did choose one pin at random for a common point, then measure from it to all the others? Repeat. Repeat.
Curious how you determined the 1 volt.

What's the difference between an orange?
With one zinc and one copper electrode, about -.82 volts.

If you say "orange" slow enough, it sounds like "gullible"...What's the difference between an orange?

A1. Because one of its legs are both the same!
A2. Because the higher it goes, the much!

heh heh, yeah, 70 gross of 9V's isnt exactly light. I looked it up; avg 9V alkaline battery is 45g. 10k of them would be 450kg or about half a ton.

What about total resistance? What would be the most effective way to measure it? Say the power is on

OK. "The power is on.":lol:

Thanks for your responses by the way, everyone.
And you got me! So you turn the power off before you measure it. But then what? Would you put the leads on two different spikes/plugs? How would you know what the total resistance is for sure? What's the method?

I don't think it can be done easily. You would have to pick a spike(2), make it the common point, and measure the resistance to all other spikes. Pick another Spike(6) and measure again. The resistance between 6 & 2 would be the same as 2 & 6. (This would be the same method for checking voltage differences.) Repeat. Repeat....until all spikes have been used as a common with all resistances recorded You may eventually see a pattern develop. 21 spikes is going to take some time. I'm tired already.
