A direct current (DC) generator is a device that converts mechanical energy into electrical energy in the form of direct current. It operates on the principle of electromagnetic induction, where a conductor moves through a magnetic field, generating electricity. DC generators are commonly used in applications requiring stable and consistent voltage, such as battery charging and powering small electronic devices. These generators consist of key components, including an armature, field windings, and a commutator. The armature rotates within the magnetic field created by the field windings, while the commutator ensures that the output current flows in one direction, providing a steady DC output.
