Galvanometer is always connected in
WebExplain why a voltmeter must be connected in parallel with the circuit. Draw a diagram showing an ammeter correctly connected in a circuit. Describe how a galvanometer can be used as either a voltmeter or an ammeter. Find the resistance that must be placed in series with a galvanometer to allow it to be used as a voltmeter with a given reading. WebApr 8, 2024 · Hint:We know that the shunt is always connected parallel to the resistance in the galvanometer.Here, in this question, the galvanometer current, resistance of the galvanometer and resistance of the shunt is given. We will use the formula for the ammeter current which is the function of all these given values.
