As more lamps are put into a series circuit, the overall current in the circuit a. increasesb. decreasesc. remains the same

b. Decreases

Explanation:

The total resistance of a series circuit is equal to the sum of the individual resistances:

(1)

Therefore, as we add more lamps, the total resistance increases (because we add more positive tems in the sum in eq.(1).

The current in a circuit is given by Ohm's law:

where V is the voltage provided by the power source and is the total resistance. We notice that the current, I, is inversely proportional to the total resistance: therefore, when more lamps are added to the series circuit, the total resistance increases, and therefore the current in the circuit decreases.
