A student arranged an electric circuit as shown alongside:



He would observe:
(1) no reading in either the ammeter or the voltmeter
(2) no reading in the voltmeter but a reading in the ammeter
(3) no reading in the ammeter but a reading in the voltmeter
(4) readings in both the ammeter and the voltmeter

Q. Arrange the following steps to verify the Ohm's law in proper sequence.
(a) Switch on the electric circuit.
(b) Move the position of the slider of the rheostat and note down the ammeter and voltmeter readings.
(c) Connect ammeter, key, battery, rheostat and resistor in series by using conducting wires.
(d) Note down the Ammeter and voltmeter reading.
(e) Connect a voltmeter across the resistor.
(f) Determine the ratio of voltmeter reading and ammeter reading in each case.
(g) Note that the ratio of voltmeter and ammeter reading are equal in each case.

Q.

Find the voltmeter and ammeter reading in the above circuit.
