Lab Activity​

Answer 1

Explanation:

Increase the current by adjusting the slider of the rheostat and take about 5 or 6 sets of readings. Note carefully ammeter and voltmeter readings in each set and record in the Observation Table. Note V/I ratio for each set of reading in the Resistance column. Thus, the ratio V : I is a constant.
