Stunning Radiant asked a question
Subject: Science, asked on on 8/9/13

The following apparatus is available in a laboratory

Cell: Adjustable from 0 to 1.5 volt

Resistor: 4 ohms and 12 ohms

Ammeters: A1 of range 0 to 3A: Least count 0.01 A2 of range 0 to 1A ; least count 0.05 A

Voltmeter: V1 of range 0 to 10V; Least count 0.5V ; V2 of range 0 to 5V; Least count 0.1 V

The best combination of voltmeter and ammeter for finding the equivalent resistance of the resistors in paraller would be

a) ammeter A1 voltmeter V1

b) ammeter A1 voltmeter V2

c) ammeter A2 voltmeter V1

d) ammeter A2 voltmeter V2

PLZ GIVE THE CORRECT OPTION WITH EXPLAINATION

​Q36. 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 :

    (a) ( + 4 mA, – 0.2 V) and ( 1 mA, 0.1 V) respectively

    (b) (+ 4 mA, –0.2 V) and ( 2 mA, 0.2 V) respectively

    (c) ( – 4 mA, + 0.2 V) and (2 mA, 0.2 V) respectively

    (d) (–4 mA, + 0.2 V) and (2 mA, 0.1 V) respectively
