WebApr 8, 2024 · Hello, What is the voltage of a voltaic cell? Some sources claim it's 1.1 V (the difference of potentials of zinc and copper). But I've also seen its being claimed to be 0.76 V (the difference of potentials of zinc and hydrogen). I know that zinc and hydrogen are the ones undergoing redox reactions and the copper only acts as a conductor, so to ... WebAug 16, 2024 · Maintaining Earth ground at altitude. Earth ground has a common potential WRT to voltage measurements taken at higher altitudes in the atmosphere (100 V/m 3) or something. To measure this difference, you can connect your voltmeter cathode to the Earth and attach the positive lead to a probe electrode at some height.
