A straight-line V–I graph for a conductor passes through the points (2V,0.10A) and (6V,0.30A).
(i) Calculate the resistance of the conductor.
(ii) Determine the current that would flow through the conductor when the potential difference is raised to 10V.
(iii) If the conductor is connected to a 12V battery for 5min, calculate the total charge that passes through it.
