### Potentiometer Circuit Measurement**Diagram Explanation:**The diagram depicts a circuit using a potentiometer to measure the voltage \( V_m \). In the circuit:- \( V_s \) represents the source voltage.- \( L \) is the total length of the potentiometer.- \( R \) is the resistance wire of the potentiometer.- \( R_x \) is the variable section of the resistance wire.- An ammeter (A) is connected in series to measure current \( I_G \).- \( V_m \) is the voltage across resistor \( R_m \).**Question 2: [5 Points]**A potentiometer is used to measure the voltage \( V_m \) as shown in the circuit above. \( L \) is the length of the potentiometer, and \( x \) is the length of resistance up to the contact point when the measurement is ready to be taken.(a) **Conditions for Measurement:** - What conditions are required for a measurement to be taken? - Does this place the system in null or deflection mode for the measurement?(b) **Calculation of \( V_m \):** - How is \( V_m \) calculated from the measured length \( x \)? Provide a mathematical expression. - No written explanation is required.

a. To make the measurement of unknown voltage Vm The ammeter must show 0A reading For more accuracy…

A potentiometer is to be used to measure the voltage Vm as shown above. L is the length of the potentiometer and x is the length of resistance to the contact point when the measurement is ready to be taken.

The windscreen washers of an old car don't work (W = 0). This could be for two reasons: the windscreen fluid tank is empty (E = 1) or the tube is has a blockage (B = 1). Being an old car, the light to indicate that the windscreen fluid tank is empty only comes on (L = 1) 75% of the time. It will sometimes comes on even if the tank has some fluid in it, with probability 0.25. Of course the tube could be both blocked and the tank empty.
