## What happens to the intensity of light as more bulbs are connected in series in your circuit?

Intensity of brightness of lamps will decrease. When you add more bulb in series their resistance will increase, as the voltage of the source is same, so the total current of the circuit will decrease.

## What are the advantages of bulb connected in series?

The biggest advantage of a series circuit is that you can add additional power devices, usually using batteries. This will greatly increase the overall force of your output by giving you more power. Your bulbs may not shine as brightly once you have done this, but you probably won’t notice the difference.

## What does it mean if bulbs are connected in series?

If a wire joins the battery to one bulb, to the next bulb, to the next bulb, to the next bulb, then back to the battery in one continuous loop, the bulbs are said to be in series. If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel.

## Why is parallel brighter than series?

Two loops, both connected to the battery, each with it’s own loads is called a Parallel Circuit. Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit.

## What are the advantages and disadvantages of connecting bulbs in parallel and in series?

Why are bulbs brighter in parallel than series? When the bulbs are in parallel, each bulb sees the full voltage V so P=V2R. Since a bulb glows brighter when it gets more power the ones in parallel will glow brighter. See, the parallel combination of resistors reduces the effective resistance of the circuit.

## What are advantages of series?

Advantages: 1. Series circuits do not overheat easily. The current that flows in a series circuit has to flow through every component in the circuit. Therefore, all of the components in a series connection carry the same current.

## How are light bulbs in series and parallel circuits?

The photograph below shows the operation of these two circuits: The bulbs in each circuit, from left to right, are a 40-W, 60-W and a 100-W light bulb. In the parallel circuit, the bulbs obviously increase in brightness from left to right. In the series circuit, the brightness decreasesfrom left to right.

## How is the life of a light bulb measured?

In the light bulb industry, the lifespan of a bulb is referred to as “Average Rated Lifetime Hours” (ARL). Average rated lifetime hours indicate how long it takes for a certain percentage of light bulbs in a test batch to fail, and are measured and labelled using hours and an “L rating”.

## Which is brighter when connected in series or parallel?

Most of the household electrical wiring & installation are wired in parallel or series-parallel instead of series as parallel wiring has some advantages over a series wiring. So we may notice that higher rated bulb glows more brightly as compared to lower wattage rated bulbs. In that case, 100W bulb glows more brightly than 60W or 80W bulb.

## Why do light bulbs glow brighter when connected in parallel?

The first two examples assume that the bulbs in parallel and the bulbs in series weren’t all (four) connected at the same time. If that was the case, those in parallel would always burn brighter. Note: the assumption that incandescent light bulbs have constant resistance is completely wrong! Resistance changes with temperature:
