Why do electrical generators experience load effects?

[Bloc911]

I was wondering why it is when you use the electricity from an electrical generator, it bogs the generator down? Shouldn't the draw off of electricity negate any sort of back flow there by making it easier on the generator to function?

Conservation of energy is immutable. When the generator is loaded, the load current produces a torque which counters the input mechanical torque. This is motor action. Generators are motors as well, & vice-versa.

Ty cabraham, I will soon be working a generator system and was curious about the effects of loading on generators. I had guessed that such was the case but figured it would be better to ask. Hopefully soon I will be able to set my system. From the figures is have been working with I should be in the clear on the power to crank the generators under load as I will have 5 generators to split the load. Hopefully dividing the torque between them should be such that even though it will still be the same overall amount the division will produce less drag on the whole. I am guessing anyway. I will have to wait until I get it up and running to test it out.

Just note that no matter what, the system will obey Conservation of Energy.
