Final answer:
Bulbs in a parallel circuit will burn equally bright.
Step-by-step explanation:
In a parallel circuit, bulbs will be equally bright.
When bulbs are connected in parallel, each bulb has its own separate path for current to flow through. Therefore, the resistance of each bulb does not affect the brightness of the other bulbs. Each bulb receives the same voltage and can operate independently, resulting in equal brightness for all bulbs.
On the other hand, in a series circuit, bulbs share the same path of current. This means that the total resistance of the circuit is equal to the sum of the resistance of each bulb. As a result, if bulbs with different resistances are connected in series, the bulb with the higher resistance will be dimmer than the bulb with the lower resistance.
