The rest positions of the needles in a Milliammeter and Voltmeter when not being used in a circuit are as shown in the figure. The 'zero error' and 'least count' of these two instruments are:(1) (+ 4 mA, – 0.2 V) and (1 mA , 0.1 V) respectively(2) (+ 4 mA, – 0.2 V) and (2 mA , 0.2 V) respectively(3) (– 4 mA, + 0.2 V) and (2 mA, 0.2 V) respectively(4) (– 4 mA, + 0.2 V) and (2 mA, 0.1 V) respectively |
