You are provided with a variable DC power supply E, a 2 \Omega standard resistor, R, a key, an ammeter, a voltmeter and other necessary materials.

Question Parts

( a )
(i) Set up a circuit as shown in the diagram above with E=3.0 V. (ii) Close the key. (iii) Record the voltmeter reading, V. (iv) Read the corresponding ammeter reading, I. (v) Evaluate V^{-1} and I^{-1}. (vi) Repeat the procedure for the four other values of E=4.5 V, 6.0 V, 7.5 V and 9.0 V. (vii) Tabulate your readings. (viii) Plot a graph with I^{-1} on the vertical axis and V^{-1} on the horizontal axis starting with both axes from the origin (0, 0). (ix) Determine the slope, s of the graph. (x) Also, determine the intercept, c on the vertical axis. (xi) What does the slope, s represent? (xii) State two precautions taken to ensure accurate results.
