a. To determine Calculate the value of resistance R v in the given d’Arsonval voltmeter for the full-scale reading of 50 V . Explanation Given data: Refer Figure P3.37 in the textbook for the circuit of d’Arsonval voltmeter. Formula used: For the given circuit, write the expression for the total resistance of the voltmeter for all full-scale reading. R v + R movement = Full-scale reading 1 mA (1) Here, R v is the resistance of resistor connected in series with d’Arsonval voltmeter. R movement is the resistance of the meter movement. Calculation: It is given that the full-scale reading of d’Arsonval voltmeter is 20 mV and current rating of the voltmeter is 1 mA . Hence, the resistance of the meter movement can be calculated as follows. R movement = 20 mV 1 mA = 20 Ω Substitute 20 Ω for R movement in equation (1). R v + ( 20 Ω ) = Full-scale reading 1 × 10 − 3 A { ∵ 1 mA = b. To determine Calculate the value of resistance R v in the given d’Arsonval voltmeter for the full-scale reading of 5 V . c. To determine Calculate the value of resistance R v in the given d’Arsonval voltmeter for the full-scale reading of 250 mV . d. To determine Calculate the value of resistance R v in the given d’Arsonval voltmeter for the full-scale reading of 25 mV .
