  Ohm's law Information - ohms law formulas
The analogy to the Lorentz force is three formulas to ohms law obvious, and in fact Ohm's law can be derived from the Lorenz force formulas for ohms law and the assumption that there is a drag on the charge carriers proportional to their velocity.
The actual content of the law is that in many cases of practical interest, the resistance of a component definition of ohms law is not a function of the applied voltage.
Ohm's law was one of the first and probably the most important early quantitative descriptions of the physics of electricity.

 Ohms Law
Likewise the linear relationship expressed by ohms law was not obvious to Ohm from fluid mechanics, because pressure drop of fluids in a line is not linear with respect of flow rate.
Ohms law states that current in amperes is equal to voltage divided by resistance.
This form of ohms law is most useful for technicians because it is easy to measure voltage with a single probe of a grounded voltmeter.

The Ohms Law chart has a center ring containing 4 items (P, I, R and E) and then an outer ring that contains equations that relate to finding out the values of the inner 4 items.
Ohms Law operates assuming a perfect world - the issue is that nothing is truely perfect and Ohms Law does not account for losses or design limitations that we may not be totally aware of.
Looking at the Ohms Law chart, you can see that if you add up the Wattages (P) of all the devices you plan to use, and divide that by the Voltage (E), you will get the Current needed (I).
