To set up a current source why do we need to place the resistances in parallel rather than than placing them in series.

A current source is a device that provides a constant flow of electric current in a circuit, regardless of the load resistance or changes in the input voltage.
Setting up a current source can be useful in situations where a constant and precise current is required, such as in electronic testing, powering LEDs, or in some types of sensors.
To set up a current source with parallel resistances, you will need to connect the resistances in parallel to the output of the current source. This will ensure that the same current flows through each resistance, as the resistances are in parallel, and the current source will maintain a constant current.
The use of parallel resistances in a current source allows for a more flexible and efficient circuit design. It also allows for the distribution of current among multiple resistances, reducing the load on each individual resistance and increasing the overall reliability of the circuit.
One limitation of using parallel resistances in a current source is that the total resistance of the circuit will be lower than the individual resistances, which may result in a higher current than intended. Additionally, the use of parallel resistances may also increase the complexity of the circuit and require additional components for proper functioning.
