potentiometers, as a commonly used electronic component, believe that engineers have already begun to contact when studying junior high school textbooks. Some basic circuit experiments arranged to verify Ohm's law will use potentiometers, also called sliding rheostats.
Is there an alternative to sliding rheostat?
principle of sliding rheostat circuit
The sliding rheostat has three pins in the circuit design symbol, the two pins A and B are fixed pins, and the W pin is an output variable sliding pin; in the application of actual circuit projects, the W pin is usually The B pins are connected together, so that the position of the W pin is adjusted by sliding to change the resistance value of the two pins A and B; this is the working principle of the circuit of the sliding rheostat

programmable sliding rheostat
Sliding varistor is widely used by R & D engineers due to its many circuit advantages; however, one of the biggest disadvantages of sliding varistor is that it belongs to a mechanical circuit component, which requires external manual manual adjustment to reflect the circuit characteristics. The range of sliding rheostat used as a potentiometer; then is there a programmable sliding rheostat instead of traditional sliding rheostat? Find an improved alternative?
