Answer Key : (c) -

(c)

We will require a voltmeter, an ammeter, a test resistor and a variable battery to verify Ohm’s law.

Voltmeter which is made by connecting a high resistance with a galvanometer is connected in parallel with the test resistor.

Further, an ammeter which is formed by connecting a low resistance in parallel with galvanometer is required to measure the current through test resistor.

The correct option is (c).



Next Question :

To decrease the range of an ammeter, its resistance need to be increased. An ammeter has resistance and range I. Which of the following resistance can be connected in series with it to decreases its range to ?

a)

b)

c)

d)

None of these
