Current, Volts, Current Density

[Guest guest]

Batteries show only " volts " . If you read fine print, they also show how many

" amps " they have inside. Amps is just like a truckload of beans. Big batteries

have big truckloads, small ones less beans.

The volts is sort of like the height of the truck. Higher trucks spill their

beans with more force, lower trucks have less force on the falling beans...I

think you get this idea..volts is force, amps is number of beans. We want to

put a stream of beans into each germ in order to kill it.

If you use a small pipe, you get less beans per minute, if a larger pipe, more

beans, assuming same trucks. Higher trucks will force more beans into the

pipe, and into you per minute. Lower trucks using same pipe will force less

beans into you per minute. A 1.5 volt battery is a very low truck and will

provide you with too few beans. A 6 volt battery is a " just right " truck, and

gives you a perfect number of beans usually. A 9 volt battery is like a truck

the height of a 2 story house, and will give you " too many " beans and could be

painful if used a long time.

If you use a large sponge you can get more total beans, versus a smaller one,

since you are providing more pathways for the beans to go. Total beans is

" current " in electrical terms, and is just like the current of a river or

stream.

But total current does not tell you how many beans each germ gets hit with.

Remember, we need a certain number of beans over a certain length of time in

order to kill the germ. And each germ has to get this amount at least, in order

to kill it.

Well, over a larger area, you have more germs. So you do need more current in

that case. Over smaller areas you can use less total current. To further

illustrate this: assume you only have ONE germ. The size of sponge needed

could be reduced to a microscopic size. If you have millions of them, you just

add more microscopic sponges until you have a large, visible sponge.

Ok, take a herpes sore. It is small but the virus is tough, can survive outside

the body, lives inside a nerve. We need a higher current for each herpes virus.

So we use a wire with a couple layers of cloth around it, which will allow lots

more current (or beans) into the small area than would a sponge. Sponges are

less conductive than thin layers of cotton cloth. So you just put the " hotter "

electrode on the herpes sore for a little time and allow the high level of

dense, packed in, beans (electrons) to hit those germs. Voila! no more herpes

AT THAT SPOT.

With a larger infection, like MRSA outbreak you use the large sponge to cover

more of it. But you need less beans (electrons) to do the job as it is

bacterial and less power is needed to kill those. It is very fast, often one

hour application to kill all of it (!!)

This little speech on beans and electricity is brought to you by the letters:
