| 1. | First, consider the Galvani potential between two metals.
|
| 2. | However, their Galvani potentials will be different ( unless the metals are identical ).
|
| 3. | Dissimilar metals in contact produce what is known also as a contact electromotive force or Galvani potential.
|
| 4. | Generally, the Galvani potential difference is measurable only when the two phases have identical chemical composition.
|
| 5. | As explained above, we can divide the voltage into two pieces : The galvani potential, and everything else.
|
| 6. | In a traditional metal-insulator-metal capacitor, the galvani potential is the " only " relevant contribution.
|
| 7. | Where the difference on the left-hand side is the Galvani potential difference between the phases ( 1 ) and ( 2 ).
|
| 8. | Therefore, as the capacitor charges or discharges, the voltage changes at a " different " rate than the galvani potential difference.
|
| 9. | At a high aqueous pH, the acid is in the anionic form and can exist in both phases according to the Galvani potential difference.
|
| 10. | When a voltmeter is used to measure an electronic device, it does not quite measure the pure electric potential ( also called Galvani potential ).
