2021-2022 Q1 A voltmeter is always connected in parallel with the element being measured, and measures the voltage between the points across which it is connected. Consider you have a basic d'Arsonval movement with internal resistance of 1002 and half scale current deflection of 0.5 mA. Answer the following: 1- How to convert this D.C voltmeter by indirect method into a multirange D.C voltmeter with voltages ranges of 10V, 50V, 250V, and 500V. 2- Draw the circuit diagram of multirange D.C voltmeter. 3- Find the sensitivity of voltmeter.
