Electric clocks can operate by several different types of mechanism: • Electromechanical clocks have a traditional mechanical movement, which keeps time with an oscillating pendulum or balance wheel powered through a gear train by a mainspring, but use electricity to rewind the mainspring with an electric motor or electromagnet. This mechanism is found mostly in antique clocks. WebI was talking to my grandma today and she mentioned to me that before they got electricity on the farm (USA for reference) they had a radio that would run on batteries.
