referenssipotentiaali
Referenssipotentiaali, often translated as reference potential, is a fundamental concept in electrical engineering and physics. It defines a zero point for the measurement of electric potential. In essence, it is an arbitrarily chosen point in an electrical circuit or system whose potential is assigned a value of zero volts. All other electric potentials within that system are then measured relative to this reference point.
The choice of a reference potential is crucial for consistency and comparability of measurements. Common choices
Without a reference potential, electric potential values would be meaningless, as they are relative differences in
