| 21. | The machine generates an electric potential difference between two metal cages inside a vacuum.
|
| 22. | :We are propagating a potential difference up the axon.
|
| 23. | The sum of the potential differences ( voltage ) is equal to the total voltage.
|
| 24. | The potential difference mentioned in the batteries and cells is usually the open circuit voltage.
|
| 25. | Is it just because the potential difference is spread out too thinly after a bit?
|
| 26. | This K + " leak " generates a positive electrochemical potential difference in the lumen.
|
| 27. | Potential difference between two points corresponds to the battery.
|
| 28. | Thus a potential difference is felt between the output or signal leads of the load cell.
|
| 29. | This potential difference can drive a current if an external circuit is attached to the terminals.
|
| 30. | An equilibrium is finally reached when the potential difference is a few times the electron temperature.
