A voltage regulator controls generator output by?

  1. Varying resistance in the circuit

  2. Varying current flow to the mechanical parts

  3. Varying current flow to generator field coil

  4. Switching the circuit on and off

The correct answer is: Varying current flow to generator field coil

A is incorrect because varying resistance in the circuit would have no direct effect on the generator output. B is incorrect because varying current flow to the mechanical parts would not directly control the generator output. The mechanical parts of a generator are responsible for converting the mechanical energy into electrical energy, but they do not directly regulate the output. D is incorrect because switching the circuit on and off would completely stop the flow of current to the generator, which would not regulate the output.
