Figure 3.1. It consists of placing a known stable resistor in series with the unknown one. First a reading is taken across that resistor and then another reading across the unknown one. Afterward the quotient between both readings is calculated.
The first reading gives
Vs= V/(Rs+Rx ) Rs
The second one gives
Vx = V/(Rs+Rx) Rx
From the quotient between both readings R can be calculated as Rx = Rs Vx/Vs
If R and R are similar in value, the voltmeter error in both readings will be similar and will cancel when taking the quotient. The need for two readings inherent to this method makes it unsuitable for sensor measurement because of the inconvenience of the needed switching when the measurement must be fast. Also when the output signal must be in electrical form, it is not possible to make the quotient by hand.Variable Resistor Electronic Symbol
Variable Resistor Electronic Symbol. As indicated by its name, a variable resistor, is a type of resistor which value is adjustable/change. Variable resistors have two basic components. The material that provides the variable resistance is called the element. and the movable component, which is used to set the resistance, is called the wiper, or brush.BMW F30 Voltage Supply Wiring Harness
