The higher the current, the more work it can do at the same voltage. Power = voltage x current. The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for.
“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
The larger the external current, the greater the required rate of chemical reactions and thus, the lower the voltage across the terminals. As long as the circuit current is significantly less than the maximum current the chemicals reactions can sustain, the voltage across the battery terminals will be close to the open circuit voltage.
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.
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.
In a battery, the number of protons and electrons in the system are fixed, causing a constant voltage that varies with the charge of the battery.As the electrons flow from one terminal to the other, the voltage drops because there are less free protons.
