Question
If you were going to connect two light bulbs to one battery, would you use a series or a parallel arrangement? Why? Which arrangement takes more current from the battery?
Advertisements
Solution
Since every lightbulb in a parallel circuit receives the same voltage as the battery, I would choose to utilize a parallel arrangement. Additionally, if a flaw causes one light to stop glowing, the other bulb keeps glowing. This guarantees that even in the event of a single bulb failure, the circuit will continue to function. Because the parallel design has a lower equivalent resistance than a series arrangement, it pulls more current from the battery. Ohm's Law (I = V/R) states that a stronger current from the same voltage source is produced by a lower resistance.
