Does the number of batteries change the brightness of the bulb?

It will if the batteries are connected in series. If they are connected in parallel, the lamp will burn longer, but not brighter.

If you were testing how the number of batteries affect bulb brightness what heads would you use on a data table?
Shut up you fat monkey
How do you change the brightness of the bulb?
Increase the voltage supply.
Does anything happen to the brightness of the bulb when you add an extra battery to a simple circuit?
We did this experiment in class, the more batteries added, the brighter the bulb will become!
What is the factor that affects the brightness of the bulb?
number and voltage of the cells in the circuit resistance of each bulb
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.
What would happen to the brightness of the bulb if you added a second bulb in with the first?
The brightness of a bulb would not change if you added a second bulb in parallel with the first.Unless, of course, the increased current exceeded the power supply's capacity causing a reduction in voltage.
How do you alter the brightness of a bulb?
You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.
Can you make a bulb glow more brightly by adding a second battery?
Yes, two batteries will make a light bulb brighter than one, provided that the batteries are placed in series. The brightness of the bulb is determined by the voltage, and placing two batteries in series rather than just using one increases the voltage.
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
How would you compare the brightness of the bulbs as you increase the number of bulbs?
-- 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 !)
Why did the light bulb change brightness along the pencil?
because the pencil take the a litte enrgy.
Is there any change in brightness when a lighting bulb is shifted in a mirror covered room?
Almost none.
