Understanding Source and Load
The definition of SOURCE is "Any thing or place from which something comes, arises, or is obtained".
An electrical LOAD is an electrical component that consumes electric power from the source. Examples of loads are lights, air compressors, fridges...
It is important to remember that a fuse box can be both a source in a load. This is because it is a junction block in between your battery and electrical accessories.

- The source is a sensor and the load is an amplifier.
- The source is a signal generator that produces various waveforms, and the load is an oscilloscope to display such waveforms.
