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.
you can make it brighter by adding another battery/cell
there will be little or no change
If you add another battery in series with the first one, then the bulb willglow brighter, and may burn out if you carry things too far.If you add another battery in parallel with the first one, then the brightnessof the bulb won't change, but the battery will last twice as long.
The bulb that glows brightly likely has a higher current passing through it compared to the dim bulb. This could be due to differences in resistance, voltage, or power ratings of the two bulbs.
lower wattage bulb
what is a conclusion for a battery powered light bulb
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
more battery's or a better bulb.
yes
Replace the battery and recharge if a rechargable battery if not it might need new bulb
