When dc generators are operated in parallel to supply power for a single load, their controls include an equalizer circuit to assure that all generators share the load equally. The equalizer circuit operates by:___________
A) Decreasing the output of the high generator to equal the output of the low generator.
B) Increasing the output of the low generator to equal the output of the high generator.
C) Increasing the output of the low generator and decreasing the output of the high generator until they are equal

A DC generator has four basic parts: a commutator, a single conductor or loop, a magnetic field, and brushes. A DC generator which is built utilizing the basic principle that emf (Electromotive force) is induced in a conductor when it cuts magnetic lines of force is an electrical machine which converts mechanical energy into direct current electricity.

An equalizer circuit operates by maintaining an equal sharing of the load between all generators in a DC generator system.

Parallel operation of DC generators is required to meet the extra load demand. Some of the conditions that must be met for parallel operation Of DC Generator is: the terminal voltage must be the same, the change of voltage with the change of load must be the same character, and the polarities of the generator must be identical.

The output voltage of the high generator is decreased, and the output voltage of the low generator is increased, once the load is shared unequally.
