When referring to the power source, it is termed the supply where the device or circuit is considered the load. The load receives energy and is used to test the electrical properties of a device. When testing devices, loads are used to simulate interactions between other loads in a system to see how sources will react to variable currents.
The power supply is what generates electricity to receiving devices, loads, or systems. AC power supplies alternate current direction and are essential for measuring current in electrical systems. DC power supplies direct and provide constant current.
