2. [5 points] (a) Vs (b) R Rx IG contact Ammeter A 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. VmRm What conditions are required for a measurement to be taken? Does this place the system in null or deflection mode for the measurement? How is Vm calculated from the measured length x? Provide a mathematical expression. No written explanation required.
