Answer:

The brightness of the bulbs decreases as you add more.

Explanation:

Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit.

hpe it help well

more brightness pooo hehe
