If the resistance between the center and the outer terminal on a 20 k ohm potentiometer reads 12 k ohms, the resistance between the center terminal and the other outer terminal is
i have 12kohms
To determine the resistance between the center terminal and the other outer terminal, we can use the concept of the total resistance of a potentiometer.
A potentiometer is a three-terminal variable resistor in which the resistance between the center terminal and either outer terminal can be varied by rotating a knob or slider. The total resistance of the potentiometer is constant and is typically given as its nominal value.
In this case, we know the nominal value of the potentiometer is 20 k ohms. We are given that the resistance between the center and one outer terminal is 12 k ohms.
To find the resistance between the center terminal and the other outer terminal, we can subtract the given resistance from the total resistance:
Resistance between the center and other outer terminal = Total resistance - Resistance between center and one outer terminal
Resistance between the center and other outer terminal = 20 k ohms - 12 k ohms
Resistance between the center and other outer terminal = 8 k ohms
Therefore, the resistance between the center terminal and the other outer terminal is 8 k ohms.
