WhatsApp: +86 18838072829Rheostats vary the amount of electrical resistance in a circuit. They proved beneficial as the use of electrical power expanded in the late 1800s. Among their many applications, rheostats helped motors start safely, controlled motor speed, maintained a constant current in battery chargers, and adjusted volume and light levels. This rheostat was used as part of Edison's first threewire ...
