The current through a lamp connected across 120 v is 0.75 a when the lamp is on. (a) what is the lamp's resistance when it is on? (b) when the lamp is cold, its resistance is one fifth as great as it is when the lamp is hot. what is the lamp's cold resistance? (c) what is the current through the lamp as it is turned on if it is connected to a potential difference of 120 v? a
