There is no simple relationship between the two.
First, how quickly a fan can move air depends on not on the voltage, but on its power. In electricity, the power is equal to voltage times current (times a power factor, which is usually close to one). Thus, you can get a certain power - say, 50 watts, or 100 watts - with just about any voltage.
Second, the force the fan has on any specific object depends on the object's size, and its precise shape. Search Wikipedia, or other sources, for "aerodynamics", as well as "air resistance", for more details.
The force of an electric current is measured in volts.
The unit for electric field is newtons per coulomb (N/C) or volts per meter (V/m).
There is no "force of electricity". Voltage is sort of like a "force" that makes electricity flow, but it doesn't have the units of force.
Watts measure power, which is the rate at which energy is transferred or used. Volts measure electric potential difference, or the force that drives an electric current. In simple terms, watts tell you how much power is being used, while volts indicate the force pushing the power through a circuit.
EMF stands for "electromotive force" and is (more or less) a synonym for voltage. Despite the name, it's not really a "force" in the physical sense (EMF is measured in, unsurprisingly, volts, while forces are measured in newtons), and is more properly referred to as a potential. See the related link for more details.
Electric field strength is measured in Volts per meter, V/m OR equivalently, Newton per Coulomb, N/C.
Generally, no. Newtons are a unit of FORCE, and EM waves convey very little force. EM waves are generally measured by Hertz (ie, their frequency), by micro-meters or angstroms (ie, their wavelength), or by electron-volts (ie, the energy of their photons).
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
volts abbr (V)
The force of an electric current is measured in volts.
Force and volts are not directly related concepts, as force is a physical quantity that describes a push or pull on an object, while volts are a unit of measurement for electrical potential or voltage. There is no direct conversion between force and volts, as they pertain to different physical phenomena.
It depends on the cable. 0 to 5000 volts the minimum bending radius is 6 x diameter of the cable. Above 5000 volts the minimum bending radius is 8 x the diameter of the cable.
Electricity
Volts are the measure of Eletro motive force. (EMF)
Volts are the "electromotive force" that is needed to "drive" the electricity through the wiring.
You require about 24 volts to power the windshield wiper.
That's the unit for the electric field. The SI units for electric field are, precisely, newtons/coulomb - or the equivalent, volts/meter. This unit doesn't have a special name.
