Determine the meter movement resistance? ii. Determine the resistance of the series Resistance R's (also referred to as the multiplier)? 3. Suppose the d'Arsonval volt-meter shown is used to measure the voltage across the 45 Q resistor as sown in the figure. What will the volt-meter read? (if it is in the switch position 1). 4. Write down the expression of the percent-error in the volt-meter reading as a function of VFR? then calculate the percent-error. Definition: %error=| (measured_value / true_value 1)| × 100%. Hint: true_value is the measured voltage difference without the extra effect introduced by the volt-meter itself. 5. Make a drawing of the percent-error as a function of VFR (changing VFR from 1V until 100V). R8 V®FR=40V R?, V7FR=35V • R6, V€FR=30V . R$, V$FR=25V .
