Dummy Load N-male is a component, component, or device that substitutes for terminating in a circuit (such as an amplifier) or an electrical output port to receive electrical power.

Dummy Load N-male A component, component, or device that receives electrical power at a circuit (such as an amplifier) or electrical output port that replaces the terminal. The most basic requirement for Dummy Load N-male is to match the power impedance that can be borne. An informal load used temporarily, usually when debugging or testing machine performance.

"Let's say you want to develop a device that drives an electric motor. You have to test your device to see if it works, but you don't have the motor to do it with. You can use a Dummy Load N-male instead, such as resistance or inductance, power, etc. should be equivalent, so do the experiment. Eventually, of course, it has to be tested on a real load."
