A micro meter has a resistance of 100 Ω and a full scale of range of 50 μA. It can be used as a voltmeter or a higher range ammeter provided a resistance is added to it. Pick the correct range and resistance combinations(s).
Why this question? Key concept : To convert a galvanometer into a voltmeter of a certain range say V, a high resistance R is connected in series with the galvanometer. To convert a galvanometer into an ammeter, a small resistance S (called a shunt) is connected in parallel with the galvanometer |
