we can trasmit the electric power between the source and destination by maxmimum 2 metres.
I think the word you might be looking for is conductivity. Look up the definition and see if this word is what you are looking for.
Increasing the transmit power of a device can improve its signal strength and extend the range of communication. However, it may also lead to increased power consumption, potential interference with nearby devices, and can violate regulatory limits set for wireless transmissions. It's important to balance the benefits with the potential drawbacks when adjusting transmit power.
Power is inversely proportional to distance. As distance from a power source increases, power dissipates or decreases. This relationship is described by the inverse square law, which states that the intensity of power decreases by the square of the distance.
It is suggested that turning up transmit power or using a high-gain antenna to increase wireless signal can increase the user's exposure to radiofrequency radiation. Scientists and health professionals are still unsure as to whether this increased exposure is detrimental to one's health.
You need one more "given": the time, i.e., how long it takes you. Work = distance x force, and power = work / time. Thus, you get: power = distance x force / time
Witricity is actually a leading company which is supplying wireless power solutions in resedential buildings. It was founded in the late 2007 after research carried out at MIT institute.
Well VHF is more for long distance and has a longer wavelength. So, it would logically require more power. UHF is more line of sight and has good in building penetration and doesnt require the transmit power that VHF would require.
Hydraulics is the use of liquids to transmit power. Pneumatics is the use of gases (usually air) to transmit power.
Light can't transmit power, but can be transformed to electricity to run motors that converts to any kind of power. You need a light source and solar panel.

If we would like to transmit the voltage that comes staright from power stations without increasing it, we would have to use wires of size of the motorway to carry it. When we increase the voltage, current decreases which means we can use less diameter wire and we can transmit the power easly. P.zak bury

By using wireless camera one can capture image and video and transfer the files into a certain distance without wire.Actually, wireless camera is used for spying purpose where a tiny spy camera is kept hidden to transmit data into another location within the range of 100 to 300 meters-but this transmitting distance can be varied depending of the transmit power of the wireless antenna.
conductivity
Yep.
FM radio station transmit power in kW, while microwave radio only transmit in 1+ W max. New microwave radio transmit power less than 1W.
The power runs through electrical circuits that are mapped out by the city.
