What is back-emf: counter-electromotive force?
If you apply a voltage, and the motor begins to spin, it will act as a generator that will produce a voltage that opposes the external voltage you apply to it. …

Why can't generators with different frequencies supply the same transmission line?
Loads notwithstanding, if you just connect a 50Hz source and a 60Hz source together, they will alternate between being in-phase and out-of-phase 10 times per second. So half the time, things would be …

Will a faster rate of change of flux improve electricity generation?
Induced voltage is proportional to the rate of change of magnetic flux, so to get more voltage, you can either use faster rotation, stronger magnets, or both.
Be aware that a number of things can go …

Can I Test Bug Zapper's Voltage With Multimeter?
I would recommend not doing that, but that's just me.
(1) your meter might not like it, even if it seems it might.
The multimeter I have at home (of the $50 persuasion) claims to have a 3000V scale. …

Putting far more mechanical energy into a generator than its electrical load
If you have a 100W electrical load and you drive 100W plus efficiency losses, say 110W, into the generator, things will be in a state of equilibrium, with 100W being converted from mechanical input power … Note you can do this with no electrical load on the generator at all. …
