A battery is a voltage source, always providing the same potential difference regardless of the current. It is possible to make a current source that always provides the same current regardless of the potential difference. The circuit in FIGURE P28.56 is called a current divider. It sends a fraction of the source current to the load. Find an expression for I_loadin terms of R₁, R₂, and I_source.

You can assume that the load€™s resistance is much less than R₂.
