Would you expect all wavelengths of light incident on a solar cell to be equally good in emitting a current?
Would you expect all wavelengths of light incident on a solar cell to be equally good in emitting a current? Not always, as the refractive index of the incident can differ depending how the light propagates through the medium.
How does a prism separate white light into ROY G BIV?
Passing a current through hydrogen gas causes a purplish glow, which passes light through a prism separating the different colors into a line emission spectrum.
Is air everywhere equal in pressure?
No. The pressure changes depending on elevation and also the current weather.
What is active pressure?
In an A.C.circuit the pressure which produces a current as dinstinguished from the voltage impressed upon the circuit.
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What does the SI unit measure meters by?
The current definition of the meter is a specified number of wavelengths of a specific color of LASER light.
What is the current status of hydrogen fuel?
Hydrogen is currently not viable. There are many reasons for this. First of all, hydrogen is not naturally occuring, so we have to extract it from water. This is done by a process called electrolysis, which is just running an electric current through water. Hydrogen itself is not a source of energy, but in reality a carrier of energy. The hydrogen is combined with oxygen in the atmosphere, and the result is water vapor. In this process, an electrical current is created, thus running a electric motor. However, hydrogen is not practical because it simply does not pack the punch that current fossil fuels do. One can go much further on a gallon of gasoline than they can a gallon of hydrogen at STP(Standard Temperature and Atmospheric pressure). The process is simply not viable at this present time.
How do you product hydrogen?
pass an electric current through water - H20, and the current will divide the water molecules into hydrogen gas and oxygen gas
How does a pressure to current converter works?
An electrical circuit is an example of an electrical pressure to electrical current convertor.
Protons are present in nucleus so how current flow with these particles as conventional current?
Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).Protons are not usually involved as current carriers, except in a solution that contains hydrogen ions (i.e., protons).

What is the current price of Hydrogen fuel?
The Answer Is The Cost Is 25000000 And that's the answer.
Can you get hydrogen back if you burn it?
Yes. When you burn hydrogen the product is water. If you pass an electric current through that water you can split it back into hydrogen and oxygen.
What do you pass through water to get hydrogen gas?
Electric Current
How does acid strength affect electrical conductivity?
The strength of an acid depends of the number of hydrogen ions in solution- the stronger the acid the more hydrogen ions there are in solution. Hydrogen ions in solution carry current, therefore the more hydrogen ions in the solution the more current there will be carried through solution.
Voltage is pressure and current is flow what opposes flow?
Reverse current.
Does platinum change water back to hydrogen and oxygen?
Does platinum change water back to hydrogen and oxygen using a current
