Internal Resistance and Constant Current Supply
Internal resistance plays a crucial role in determining whether an energy source will supply a constant current into a load. Here's how it works:

Internal Resistance and Load Resistance Comparison
- When the internal resistance of an energy source is zero, it means that the source can supply an infinite amount of current into the load without any resistance. This results in a constant current flow regardless of the load resistance.
- If the internal resistance is greater than zero but less than the resistance of the load, the current supplied into the load will vary based on the load resistance. This means that the energy source will not provide a constant current output.

Zero Internal Resistance
- A constant current supply into the load is achieved when the internal resistance of the energy source is zero. In this scenario, the internal resistance does not limit the current flow, ensuring a consistent current output to the load.
- With zero internal resistance, the energy source can adjust its voltage output to maintain a constant current flow, irrespective of the load resistance. This results in a stable and reliable power supply for the load.
In conclusion, an energy source will supply a constant current into the load when its internal resistance is zero. This allows for consistent current output regardless of the load resistance, ensuring a reliable power supply.
