Electromotive Force: Terminal Voltage
The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).

What is a terminal voltage of a battery?
The point at which the seat of EMF is connected to the internal resistance of the battery is inaccessible. The potential difference between the terminals of the battery is called the terminal voltage of the battery. When the battery is not part of a circuit, the terminal voltage is equal to the EMF.
What is the difference between 0V and 12V battery terminals?
Neither battery terminal is at any specified voltage, such as 0V or 12V, as the battery terminals are isolated from any external voltage so they have no reference to any voltage. There will just be 12V difference between the two battery terminals, and they are floating.
What is battery voltage?
At its most basic, battery voltage is a measure of the electrical potential difference between the two terminals of a battery—the positive terminal and the negative terminal. It’s this difference that pushes the flow of electrons through a circuit, enabling the battery to power your devices.
What is the difference between terminal voltage and open-circuit voltage?
Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. Open-circuit voltage (V) – The voltage between the battery terminals with no load applied. The open-circuit voltage depends on the battery state of charge, increasing with state of charge.
What is the difference between terminal voltage and EMF?
The potential difference between the terminals of the battery is called the terminal voltage of the battery. When the battery is not part of a circuit, the terminal voltage is equal to the EMF. You can deduce this from the fact that when the battery is not part of a circuit, there can be no current through the resistor.
Do batteries have different voltages?
Normally, since batteries only have two terminals, their voltage is the difference between their points (in this case, yes 12V ). If you add more elements to your circuit, you can get different references and get other voltages. simulate this circuit – Schematic created using CircuitLab
