-- If the bulbs are in parallel, then the addition of a bulb has no effect

on the brightness of those that were there before.

-- If the bulbs are in series, then the addition of a bulb causes the brightness

of those that were there before to decrease.

(And I wasn't even there when you did the experiment !)

How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a series circuit?

In a parallel circuit, each bulb receives the full voltage of the power source, so all bulbs shine at their full brightness. In a series circuit, the brightness of each bulb decreases as more bulbs are added because the voltage is shared among all bulbs.


What happens to to the speed of a motor if i increase or decrease the number of bulbs in a circit?

If you increase the number of bulbs in a circuit, the resistance in the circuit will increase, causing the motor's speed to decrease. If you decrease the number of bulbs, the resistance in the circuit will decrease, causing the motor's speed to increase.


What happens to the brightness of light bulbs when more batteries are added Why?

Adding more batteries to a circuit with light bulbs will increase the brightness of the bulbs. This is because the additional batteries will provide more voltage, which allows for a higher current to flow through the circuit. As a result, the bulbs will emit more light due to the increased energy supplied.


What do you notic about the brightness of the bulbs in the parallel circuit as you added more bulbs to it?

In a parallel circuit, as more bulbs are added, the overall brightness of the bulbs remains constant. This is because each bulb gets the full voltage of the circuit and operates independently of the other bulbs. The individual brightness of each bulb may decrease slightly due to the increased current draw, but the overall brightness of the circuit remains fairly consistent.


What do you notice about the brightness of the bulbs in the parallel curcuits as you add more bulbs to it?

Nothing if the current capacity of the circuit is not exceeded. The extra bulb will draw more current and if the limit is not reached all bulbs will continue at their rated brightness. If the current capacity is overrdrawn either the circuit breakeer will break and stop all lights or if the capacity is not fused all lights will dim.

You are building a string of lights using several bulbs how is the brightness of the lights related to whether you connect the bulbs in series or in parallel?

Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.

Would the brightness of a parallel circuit of 3 globes increase or decrease when a fourth is added?

The brightness would remain constant but the power draw will increase. If the circuit was series wired, the brightness would go down as you added bulbs.


How are light bulbs efficiency increased?

The brightness of a standard bulb is directly proportional to the amount of voltage drop across the bulb itself. Thus, to increase the brightness :-Pass more current across the bulb by reducing the resistance of the circuitIncrease the voltage across the bulb, or the circuit. Change the supply.


How to compare the brightness of the old light bulbs to the new energy effiecint bulbs?

Use a phone app like light meter which uses the camera to give a luminosity level.


What happens to the brightness of the light bulbs in a parallel circuit if we add more light bulbs.?

In a parallel circuit, adding more light bulbs does not decrease the brightness of the existing bulbs. Each bulb operates independently and receives the full voltage of the power source, so their brightness remains consistent regardless of how many bulbs are added. However, the total current drawn from the power source will increase with each additional bulb.


What happens to to the speed of a motor if i increase or decrease the number of bulbs in a circit?

If you increase the number of bulbs in a circuit, the resistance in the circuit will increase, causing the motor's speed to decrease. If you decrease the number of bulbs, the resistance in the circuit will decrease, causing the motor's speed to increase.

The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?

ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.


What is the functionality of dimmable light bulbs and how do they differ from regular light bulbs?

Dimmable light bulbs allow you to adjust the brightness of the light they emit, giving you control over the ambiance in a room. They differ from regular light bulbs in that they can be adjusted to different levels of brightness, whereas regular light bulbs have a fixed brightness level.


What happens to the current in the other lights if one light burns out in a series circuit?

It depends what is the outcome of burning. If that light has created open circuit, circuit will break and there will not be any current. But if there is short circuit means overall resistance is decreased. Thus current will increase. Besides overall brightness will also increase. Thus, if in a series lesser the number of bulbs more will be brightness.
