What does voltage represent. Voltage electric potential difference electric pressure or electric tension is the difference in electric potential between two points which in a static electric field is defined as the work needed per unit of charge to move a test charge between the two points. In a simple battery circuit the ground point is usually the minus terminal of the battery. So if someone says that this point is 5v they usually mean it s 5v compared to ground. What does voltage mean.
It s common to define a zero point 0v or ground in a circuit. In the international system of units the derived unit for voltage potential difference is named volt. What does voltage mean. You can t say anything about the voltage without comparing it to another point.
