Electrical Question. Maximum voltage possible via one watt.

Is anyone Capable of giving me an equation to figure out the Maximum voltage possibility of a single Watt?

I would need maximum voltage, and minimum possible amps.

If this has already been discussed at length, i have not been able to find it via a few hours of searching, and it would be fun to learn.

Voltage, current, resistance and power all have a symbiotic relationship that is expressed by Ohm's law.

Power, expressed in watts is merely the voltage (E) multiplied by the current (I). P= ExI.

To find the maximum voltage you would divide the power by the current. P/I=E.

For one watt of power it is 1/I=E. One watt with a current of 1 milliampere (one-one thousandth of an ampere) would equal 1,000 volts.

Biggest problem is that power is a result, not a beginning. You need both voltage and current to generate power.

Thank you, I wasn't trying to figure it out for Practical use, but now that you have explained it as such, i think i should have a much easier time understanding it. ^_^

Whenever i would look for said conversion i would get an equation, with no details as to how to complete it, so i thank you ^_^

Glad I could help. Your next assignment is to always use a capital I when referring to yourself and to stop randomly capitalizing words in the body of your paragraphs. Randy Scluthz Member

Very well my friend.
I will do my very best, Though, I sucked at D.O.L. in school and have been mainly focusing on the grammar since then.
Thank you for reminding me I do that haha.

(I am humored you noticed that I randomly capitalize various words however. :P)

Also, I was curious if I have this correct.

1 Watt, Is equivalent to lets say, .50 Milliamperes and 500 volts?

So given zero resistance, at any given time, a watt is 1000 for either party but no less than 1 volt or 1 milliampere yes?

With zero resistance (which is a hypothetical idea, all circuits have some resistance) then your other parameters voltage and amperage are undefined because division by zero is meaningless.

It is possible to have very high voltage, very low current and almost no power. A good example is rubbing your feet on the carpet and sparking someone. You can generate tens of thousands of volts in that spark, but essentially no current or power.

In theory , 1 watt , with infinitesimal current , plugged into the equation would result in infinite voltage . But such intellectual number games have little practical use .

However , just for conversational purposes , you might look up the watts , voltd and amperage of a Tazer and see what the numbers come out to . I suspect the numbers for watts are not very large ?

God bless

Ok, So this is more complicated than I had initially imagined.
BUT!
It is also more promising ^_^

I will have to experiment a bit to find out if I can have some fun with this new information. Show Printable Version Email this Page
