Parallel bulbs are more bright than those in series because each bulb receives the same voltage as the circuit.
Which light bulbs burn brighter in series or parallel?
To answer this question, it is first necessary to understand the difference between a series circuit and a parallel circuit. In a series circuit, the bulbs are connected one after the other, so the current has to flow through each bulb in turn. This means that each bulb receives a lower voltage than in a parallel circuit, where the bulbs are connected side by side.
So, which type of circuit results in brighter bulbs? The answer is parallel. This is because each bulb in a parallel circuit receives the full voltage of the circuit. This means that more current flows through the bulb, and hence it produces more light.
There are some instances where you might want to use a series circuit instead of a parallel one. For example, if you were trying to create a dimmer light, you would use a series circuit because it would result in each bulb receiving a lower voltage.
However, in general, if you want your light bulbs to be as bright as possible, you should connect them in parallel.
