Generator vs. Dynamo: Know the Difference
By Shumaila Saeed || Published on January 25, 2024
A generator is a machine that converts mechanical energy into electrical energy, while a dynamo is a specific type of generator that produces direct current.
Key Differences
Generators encompass a broad category of devices converting various forms of mechanical energy into electrical energy, whereas dynamos are specifically designed to produce direct current (DC) electricity through electromagnetic induction.
