가변저항이라는데, potentiometer 와의 차이를 모르겠다.

포텐쇼미터는 전위차계로 번역을 하고, 레오스텟은 가변저항으로 번역을 하나?

| What is Rheostat? The rheostat is composed of a resistive material that is used to control the voltage to the load. The setting of the rheostat can be adjusted by rotating a handle. This device is used to control current flow through a circuit Difference between Potentiometer and Rheostats: 1) Potentiometer has two fixed resistors and a variable resistor, whereas Rheostat has only one variable resistor. 2) Potentiometer is mainly used for mechanical applications, whereas rheostats are primarily used for electrical applications. 3) The potentiometer is available with dials that help to read its setting value from outside of the circuit board, etc. 4) Potentiometers are available with a linear output, whereas Rheostats are available in logarithmic output. 5) Potentiometers are cheaper than Rheostats. 6) Both potentiometer and rheostat are used to control voltage. |

포텐쇼미터는 단자가 3개라서, 중앙의 것과 양 끝단의 하나를 사용하면 가변저항 처럼 사용은 가능하지만
본 목적은 전압의 분배라는 새로운 사실을 알게 됨(!)
A potentiometer is basically a variable voltage divider; as the knob on the device is turned, a sliding contact creates a voltage divider between the input and the two outputs. In other words, a potentiometer is simply meant for voltage division. With a rheostat simply being a potentiometer with infinite resistance at the second output, it modulates total power received by the load connected to the output. If the rheostat and load resistance are equal, then maximum power is transferred to the load component. |
