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.
Depends on the capacity of the power supply. If the power supply can push enough amps nothing will happen to the brightness. If the power supply is inadequate, each lamp will dim a little.
CommentPower supplies don't 'push' current into a circuit; current is 'drawn' from the supply to the load.
"nothing happens" the brightness of the bulb is depends on the voltage since more bulb are added in the parallel circuit voltage remain same but the current drawn will increase with no of bulb added..
in practical house wiring has the same case..... you can observe easily.
what happens is as you add more light bulbs the brightness begins to dim.This is because the bulbs are sharing power from the same source. If you want to make the bulbs brighter you must increase the amount of cells in the circuit;hope this helps.
The brightness of the bulbs will not be effected. The circuit will just be made longer.
The brightness of each individual bulb shouldn't be affected, if you have enough power to keep the voltage constant.
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
-- 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 !)
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
Bulbs that are connected in parallel would be the same brightness as a bulb on its own. If the bulbs were in series with other bulbs, then they would be dimmer. The voltage would drop across a series.
the bulbs would be very bright seeing as the two or more light bulbs have very easy excusable paths for electricity to flow and get to the light bulbAnswerBecause the voltage across each branch of a parallel circuit is the same, each lamp will be subject to its rated voltage and, therefore, will operate at its rated power output.
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.

The brightness of three bulb would be mare than one

Neither. Connecting lamps in parallel subjects each lamp to its rated voltage, so they will each operate at their rated power (therefore brightness).
the voltage across each is the same
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.
Two bulbs connected in parallel are brighter than two connected in series. The resistance of the circuit is lower, electrons can flow more easily.
since all the bulbs are connected in parallel the voltage supplied for all the bulbs are same......so third bulb also glows with the same brighteness......this is same as the tube lights connected in our house.............
Bulbs in a parallel circuit draw the same amount of current, so each will display the same brightness. Bulbs in a series circuit share the current so all bulbs will appear dimmer.
If all the bulbs are connected in parallel, and there is enough current, yes, the brightness will be the same. The voltage (which is the amount of energy in every charge), remains the same for all bulbs
Bulbs that are connected in parallel would be the same brightness as a bulb on its own. If the bulbs were in series with other bulbs, then they would be dimmer. The voltage would drop across a series.
