Question 6
Easy

A student investigates how the current through a filament bulb changes with the potential difference across it. The student's results are shown in the graph below.

A line graph showing how current in amperes (A) varies with potential difference in volts (V) for a filament bulb. The x-axis is labeled 'Potential difference (V)' and ranges from 0 to 12 V with vertical grid lines every 1 V. The y-axis is labeled 'Current (A)' and ranges from 0.0 to 3.0 A with horizontal grid lines every 0.2 A. A smooth curve starts at (0,0) and curves upwards, passing through (2, 1.0), (4, 1.6), (6, 2.0), (8, 2.2), (10, 2.4), and (12, 2.5). Point A is labeled on the curve at the coordinate (4, 1.6). Point B is labeled on the curve at the coordinate (10, 2.4)..

Use the values of potential difference and current at Point A and Point B on the graph to complete the table below.
