Does increased load on a generator require more mechanical work.

2.83K views

ECE major here that slept through all his power classes. Say I have a basic single-phase generator like the kind you get at Home Depot. If I have long string of irons and light bulbs (essentially purely resistive loads) and draw more than the rated wattage, what happens? My intuition says that the engine must work harder, but what is the specific mechanism that causes this.

From the practical side it is true.

I’m a former ECE major and also a live event audio engineer. I’ve stood next to a large deisle genny during a hardcore metal show and when the lighting director blasted the audience blinder lights you could easily hear the genny motor working harder.
