Is a Norton battery a constant current source?

in the Norton model the battery is a constant current source in parallel with the internal resistance. if the internal resistance is very low compared to the load, the battery is connected to, looking at it as a Thevenin model (a voltage source) makes more sense.

Is a battery a constant voltage source?

A battery is a time-varying constant voltage source. In order to understand this a little bit better, you have to understand why an AC-DC power supply is not constant voltage. The source of the electrons across an AC-DC converter comes from free electrons on a conductor.

How does a power supply provide a constant current?

As you can see the power supply will try to provide a constant current by reducing the output voltage. Characteristics of Constant Current Source: Fixed Output Current: The current supplied by a CC source remains constant. Varying Voltage: The voltage adjusts based on the resistance or impedance of the load.

What happens if a battery reaches a higher voltage?

If you're trying to output more current than your battery can source, than the voltage across the load goes down. V=IR; in the beginning of the discharge (cycle) there is more current coming out of the battery, which shows up as a higher voltage, and in the end, there is less, which translates into a lower voltage.

How do you know if a battery is connected to a current source?

if the internal resistance is very low compared to the load, the battery is connected to, looking at it as a Thevenin model (a voltage source) makes more sense. if the internal resistance is very high compared to the load the battery is connected to, looking at it as a Norton model (a current source) makes more sense.

Why is a battery considered a voltage source?

As the chemistry shifts with discharge (or charge) the no load voltage changes slightly and the internal resistance changes as well. A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a battery is not an ideal voltage source.
