I suppose it's C. All the other answers are everything but accurate to me
Answer:
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.
No, to multiply or divide. Yes, to add or subtract.
The first object is also negatively charged that is why people say opposites attract. have a good day!
