I tried to import a spreadheet for you but I coouldn't make it come through, if you email me I'll send it to you, like1m@yahoo.com

You can fill in the two variables, just write it in excel and you will be able to calculate your values for voltage and current dependent on the resistance for any given values. All answers here are correct as it is the basic premise of
Ohms law, but you asked for a chart. You do need to know the resistance though. The interrelation is such that for at a given voltage with infinate resistance there will be no current (flow), for that same voltage with minimum resistance there will be maximum current (flow) this would be referred to as a dead short and is comparable basically to welding. Either extreme is not normally practical unless you are turning the power "off" in one case or welding in the other (dead short). Dependent on the requirement usually the interrelation is desired to be somewhere in the middle. There is also the element of reactance which is slightly more dynamic that static resistance. but for now this is what your auto calc chart should look like....

Input ohms & volts to autocalc Amps

Input OhmsInput VoltsI=V/R
200 24 0.12

Input ohms & Amps to autocalc Volts

Input OhmsInput AmpsV=I*R
200 0.12 24

There is no conversion because they are different types of quantities. Amps are units of current and Volts are units of potential. These units are related by the amount of resistance (typically measured in Ohms) in the formula V = I * R. V=potential, I=current, and R=resistance. If this is still confusing, think of it in terms of water: a fire hose and a garden hose have the same potential (they have to because they come from the same water line, assuming there is no pump between the hydrant and the fire hose). The fire hose obviously has a lot more current because the area is much larger meaning there is less resistance to the flow of water. Hope this helps.

There is really no such chart. The relationship is

Volts = Impedance * Amps

where impedance can be almost anything depending on the circuit..

The most simple impedance is a single resistor (R, in units of ohms), then
Volts = R * Amps

but most circuits are far more complex than that.

hope this helps!

There is a relationship between the two forces but, you need more info.

The easiest way would be to make a table in EXCEL and enter the values you know and set the formula up to calculate the result.

You have to know the resistance in the circuit.

V = I * R,

where the current I is in amperes.
