WebYou can discover the right resistance to add by trying it out. Choose the largest high resistance you are offered. Connect it in series with the galvanometer and connect to a 1.5 V cell, just for an instant. Does your voltmeter read 1.5 V, as you wished? If it reads more, you do not have enough resistance in it: add more resistance. WebTo convert your galvanometer to a voltmeter reading, say, 5 V when the pointer is at the end of the scale, you must add a large resistance in series, as in the diagram. The …
Conversion of a Galvanometer to Ammeter and Voltmeter?
WebA galvanometer is converted into a voltmeter by connecting high resistance Rh in series with galvanometer as shown in Figure 3.74. The scale is now calibrated in volt and the range of voltmeter depends on the values of the resistance connected in series i.e. the value of resistance is so adjusted that only current Ig produces full scale ...

Notes on How to Convert a Galvanometer into a Voltmeter?
Web23 de fev. de 2024 · 1. Find a voltage scale on the needle's dial. Choose one that matches the setting you chose on your voltmeter's knob. If there is no exact match, read from a scale that's an easy multiple of the setting. For example, if your voltmeter is set to DC 10V, look for a DC scale with a max reading of 10. WebA moving coil galvanometer is an instrument which is used to measure electric currents. It is a sensitive electromagnetic device which can measure low currents even of the order of a few microamperes.
