# what is the resistance of hydrogen?

If I were to connect a bettery to the two sides of a container that contain only hydrogen gas, and its not dense (it's pressure is one atmosphere), what would it's resistance over the length of the container be?

• What's the container made of? ;-) – Oli Glaser Jul 14 '12 at 14:32
• a non conductive metirial, I want the electrons to only move through the hydrogen – Someonation Jul 14 '12 at 15:00
• Yep, I was just kidding around... – Oli Glaser Jul 14 '12 at 16:02

• @Someonation - It's the length but also the height and width! Twice as long = twice the resistance. Twice as high or wide = half the resistance. So for a container 1 m long, 3 cm high and 5 cm you would have to calculate 100 M$\Omega$ cm x 100 cm / (3 cm x 5 cm). Then the unit is right: $\Omega$ (what they call dimensional analysis). If you increase pressure the resistance will decrease, but I have no idea how the two are related exactly. – stevenvh Jul 14 '12 at 15:15
