What´s the voltage available for an inhatation, if  needed to control an asthma attack in a jumbo flight?

What?  Why would you need voltage to take an inhalation?  Are you talking about the machine?  Just get a hand held fast acting inhaler.  Ihe doctor will give you a script for it.  Good luck.

For a wye-connected machine:\nThe phase voltage (measured between a-b, b-c, or a-c) is (SQRT(3))* the line voltage (a-n, b-n, or c-n). In this case, connect your invertor across a-n, b-n, c-n (this may mean breaking the "common" neutral connection).\n\nFor a delta-connected machine:\nThe phase voltage equals the line voltage. In this case, connect your invertor across a-b, b-c, and a-c.\n\nWhich polarity you choose for the three connections will determine rotation - make sure your resultant rotation matches that on the machine nameplate, or you'll likely burn it up due to insufficient cooling...

You'll need to provide a little more information in order to have your question answered properly.  AC or DC? Input voltage?  Fixed or variable output voltage? If variable, over what range? If fixed, what is the desired output voltage?  Output current?  How critical is the load regulation?\n\nAs you can see, the answer to your simple question can be a bit complicated :)

You'll need, as the name may suggest, a voltmeter.  Also applicable is a multimeter - which you'd then set to voltmeter mode.\n\nAt which point you'd just put one contact on one one end of the battery, and one on the other, and see what the equipment reads.\n\nMy money's on 1.5V :)

You cannot, as was stated earlier.  You need to get a motor rated for 240VAC. You do have the option of using a step-down transformer (or step-up as the case may be). Of course, transformers aren't cheap either, so I would definitely recommend getting an expert in to look at the problem and help you find a solution.

Try a damping circuit.

I believe the minimum is 4 volts. But it also has to due with blood chemisrty. If you have a high iron level in your blood the voltage can drop as low as 2.8 volts because you have better conductivity. Most importantly is the duration of exposure, even low volts over a minute or 30sec can disrupt the AV node in your heart. On a off side, if you have a pace maker a strong static shock could potentially do it.

In case of hyperpolarization, the voltage of a neuron is about 70 millivolts (mV). Physics part is very hard and complicated, also requires high level physics and math knowledge; I don't think it should be done here.

WELL..IF YOU ARE GOING TO CHANGE A DISLEXIC TO ACCEPT ELECTRICITY OR A LIGHT BULB THEN YOU BETTER MAKE SURE EVERYTHING IS UP TO CODE...YOU WILL DEFINATELY NEED A 220 VOLT SERVICE CONNECTION..

Window units run off of 110 voltage x 2 = 220 voltage. Central air runs off 220 voltage. Central air circulates much better than window units. I'd opt for central air.

En=-(13.6)/n^2eV\nE1=-(13.6)eV\nE3=-(13.6)/9eV\ndelta E=E3-E1=hv\nhv=12eV\ntherefore,v=(12*1.6*10^(-19))/(6.626*10^-34)\nv=2.8976*10^15hz

First, what is the input voltage and the desired output voltage?  Is the output voltage fixed, or do you need a range of adjustment (taps)?  Do you need isolation between the input and the output?  If not, an autotransformer (single winding) might be acceptable.  What is the frequency, and is it single phase, three phase Y, or three phase delta?\n\nNext, what is the power rating?  Small transformers are usually rated in output current, whereas larger transformers are rated in KVA.  This is the maximum load;  a smaller load would not be a problem.\n\nFinally, what are the mechanical factors?  Does it need to be hermetic or can it be open frame?  Do you want terminals or wire leads?  What shape and size?  What is the mounting?\n\nIt's not really that hard.  Usually you can browse through a catalog and find the transformer you need in minutes.

You can use an integrated circuit, like LTC6906 from Linear Technology which goes up to 1MHz at 2.25 - 5VDC supply,\nsee:  http://www.linear.com/pc/downloadDocument.do?navId=H0,C1,C1010,C1096,P9790,D6998\nAlternative: MAX5094A by Maxim,  see:  http://www.maxim-ic.com/quick_view2.cfm/qv_pk/5017\nI didn't have the time to check the output power, but if it's not enough, a simple emitter stage transistor will do.

The unit would be the volt: http://physics.nist.gov/cuu/Units/units.html

i think you are right, you only need one.\n\nw = h*c/wavelength-eV\n\nboth should give the same w, about 1.9eV, \n\nwavelentgh = h*c/w

The deciding factor here would be the Utility Company Service Entrance. THAT cannot be rewired by you! The other two points ( Low side of transformer and Motor Windings) can easily be configured either way by simply rewiring the 3 windings on the motor, and the 3 windings on the output of the transformer.\n\nOptimum efficiency will be DELTA-DELTA-DELTA or STAR-STAR-STAR...Either way no 'ground loops' to cause loss.

Actually it's a question in physics. I will try to explain it anyway:\nassume we have two windings w1 and w2 with  n1 rounds and n2 rounds respectively. If an A.C. voltage of V1 is connected to w1 then a voltage V2 will be induced in w2, satisfying the following equation:\nV1/V2=n1/n2 and for currents we have: I1/I2=n2/n1\nand it doesnt convert ac to dc to do so we should use a rectifier such as bridge rectifier etc
