Question

how does the resistance change as you add bulbs to a series circuit?
the resistance does not change.
the resistance decreases.
the resistance increases.

Explanation:

In a series circuit, the total resistance is the sum of the individual resistances of the components (like bulbs here). When we add more bulbs (resistive components) in series, we are adding more resistance values together. So, the total resistance of the circuit increases as more bulbs are added.

Answer:

The resistance increases.
