7.3: Electric Potential and Potential Difference

Voltage is not the same as energy. Voltage is the energy per unit charge. Thus, a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other because (Delta U = qDelta V).

20.1: Batteries and Simple Circuits

The key difference with a real battery is that the voltage across its real terminals depends on what is connected to the battery. In the example above, the battery has a voltage of (6text{V}) across its (real) terminals when nothing is connected, but the voltage drops to (4text{V}) when a (2Omega) resistor is connected.

What is Battery Voltage?

A volt is a potential difference across a conductor when a current of one ampere (Amp) dissipates one watt of power. Voltage is then defined as the pressure that pushes electrons (current) between two points to enable them to power something. Battery voltage refers to the difference in charge due to the difference in the number of …

Both the battery types had pouch cell geometry with nominal voltage 3.85–4.4 V. 10 batteries of Type-1 with max capacity 3.0 Ah and 8 batteries of Type-2 with max capacity of 3.5 Ah were used.

electromagnetism

Electromotive force, abbreviated as E.M.F and denoted by $varepsilon$, is not a force. It is defined as the energy utilized in assembling a charge on the electrode of a battery when the circuit is open.Simply, it is the work done per unit charge which is the potential difference between the electrodes of the battery measured in volts.

19.1 Electric Potential Energy: Potential Difference

Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since ΔPE = q Δ V ΔPE = q Δ V. The car battery can move more charge ...

6.12: Battery characteristics

The actual voltage appearing at the terminal needs to be sufficient for the intended application. Typical values of voltage range from 1.2 V for a Ni/Cd battery to 3.7 V for a Li/ion battery. The following graph shows the difference between the theoretical and actual voltages for various battery systems:

Making Sense of Battery Ratings

This is one reason why batteries that are referred to as 12V batteries may have a different Wh number – it depends on if the common 12V or the nominal 12.8V voltage is being used. It might be better to call it a 12V system, thus allowing for the range of Volts that work within that system.

Voltage

Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points.
