Complete the table below. State what physical quantity the instrument measures. Also state the unit used for that measurement. Instrument
Quantity measured Ohmmeter 3. Sample Paper 2018, Question 9
A student investigated the relationship between the potential difference (voltage) across a resistor and the current flowing through it. The circuit diagram below shows the arrangement of the apparatus used by the student.
Unit
A )Fig. 30.25
V
Examine the circuit diagram and answer the questions below. a. The instrument labelled V measures voltage. Name instrument V. b. The instrument labelled A measures current. Name instrument A. c. In the circuit diagram above, draw a circle around the symbol for the switch.
d. The student found that current is proportional to voltage for this resistor. Using the axes provided, draw a sketch of a graph to show this relationship.
