The phrase "air voltage" is correct and usable in written English.
It can be used in contexts related to electrical engineering or physics, particularly when discussing voltage levels in the atmosphere or in relation to electrical systems.
Example: "The air voltage in the region was measured to determine the potential for electrical discharge during the storm."
Alternatives: "atmospheric voltage" or "voltage in the air".
The way it works is that users put their iPad 2 into the jacket, place it on the pad and let the Air Voltage system charge the tablet – no cables required.
Hitachi Maxell, in cooperation with Murata, has announced [JP] the so-called Air Voltage for the Japanese market today, a combination of a wireless charging pad (dubbed "Energy Stand") and jacket ("Energy Cover") specifically for use with the iPad 2. According to Maxell, the device is the first of its kind (mass-produced).
The performance of the stack for various air fan voltage was evaluated and an optimal value was concluded.
The performance of the present YZFC-OA stack showed an optimum for air fan voltage at 9.0 V.
The effects of spinning parameters, including air pressure, voltage, and solution injection rate on the morphology and diameter of fibers were investigated.
Thus, many engineering applications containing strings and ropes such as open air high voltage transmission lines, bridges, and structures may require fractional derivatives to model them accurately.
The present work evaluates the effect of current (c), pulse-on time (p) and air gap voltage (v) on metal removal rate (MRR), tool wear rate (TWR), radial over cut (ROC) on electric discharge machining of Al 4Cu 6Si alloy–10 wt.% SiCP composites.
The effects of some operational parameters such as solution pH value, discharge voltage, air flow rate and air moisture on COD removal were investigated.
Four spray parameters; current, voltage, air pressure and spray distance were evaluated using the Taguchi design.
In dry air, the actual voltage over the air-filled gap limits the maximum pressure because of electrical breakdown (Paschen curve minimum).
The whole scanning process was executed in air at a voltage of 45 kV with a current of 200 μA, a dwell time of 200 ms and a step size 850 µm.
