A torch bulb is marked “3.0 V, 0.30 A”.
(i) Determine the resistance of the filament when it glows at its marked values.
(ii) The same bulb is connected to a single dry cell of emf 1.5 V whose internal resistance is negligible. Calculate the current that will pass through the filament.
(iii) Based on your calculation in part (ii), predict whether the bulb will glow with normal brightness, dimly or not at all. Give a reason for your answer.
