Physics for IGCSE & O level - Magnets And Currents (Section 3 - No. 43)
What is the basic function of the commutator in a DC generator?
To reverse the current every half cycle.
To provide AC power.
To supply electricity to the field coils.
To control the speed of the generator.
Vysvětlení
The commutator reverses the current direction every half cycle, allowing the DC generator to produce direct current.
