ODG (Origin Data Global)
What is a Rheostat? Types, Applications & Guide What is a Rheostat?. A rheostat is a variable resistor used to control the current flow in a circuit. Its basic principle is based on Ohm's Law, which states that voltage is directly proportional to current and inversely proportional to resistance. The rheostat controls the current by providing an adjustable resistance. It is essential for applications requiring changes in electrical flow, such as controlling motor speeds, adjusting light intensity, or regulating heating elements...
