When two light bulbs are connected in parallel, which is true?
Understanding Light Bulbs Connected in Parallel
When dealing with electrical circuits, understanding how light bulbs work when connected in parallel is essential. In this scenario, we have two light bulbs connected to a battery in parallel. Let's explore the characteristics of this setup:
a. The total resistance is less than the resistance of either bulb alone.
When light bulbs are connected in parallel, the total resistance decreases compared to when the bulbs are connected in series. This is because the current has multiple paths to flow through, reducing the overall resistance in the circuit. Therefore, option a is correct.
b. The voltage provided by the battery is split evenly by each bulb.
In a parallel circuit, each component receives the full voltage provided by the battery. The voltage is not split between the bulbs; instead, each bulb receives the full voltage independently. Therefore, option b is incorrect.
c. If one light burns out then neither will light.
One advantage of connecting light bulbs in parallel is that each bulb operates independently. If one bulb burns out, the other bulb will continue to light up as it is not affected by the failure of the other bulb. Therefore, option c is incorrect.
Overall, when two light bulbs are connected in parallel, the total resistance is indeed less than the resistance of either bulb alone. This setup allows each bulb to operate independently and ensures that the failure of one bulb does not affect the other. Understanding the behavior of light bulbs in parallel circuits is crucial for designing and troubleshooting electrical systems.
Help pls,When two light bulbs are connected in parallel, then the total resistance is less than the resistance of either bulb alone. (a)
When two light bulbs are connected in parallel, the total resistance is less than the resistance of either bulb alone. This characteristic is due to the multiple paths for current to flow through in a parallel circuit, reducing the overall resistance. Additionally, each bulb operates independently in parallel, ensuring that the failure of one bulb does not affect the other. Therefore, option a is the correct statement regarding light bulbs connected in parallel.
