In a parallel circuit with up to four light bulbs would removing one light bulb affect how bright the rest of the light bulbs are? or what
please pelase pelase answer me!! i have a test today.

It depends on your power source. In theory, if you have a voltage source and four light bulbs connected in parallel, removing one light bulb will not change the brightness. The voltage source keeps the voltage constant, so the light remains constant. Remember, in a voltage source, the voltage remains constant, the current may vary. In theory, if you have a current source connected to four light bulbs in parallel, removing one light bulb will change the brightness. The current source will keep the current constant, the voltage may vary. Removing one light bulb will cause that the current will be redistributed, thus other light bulbs will be brighter.

No, in a parallel circuit each bulb receives the same voltage, removing one or two will not affect the brightness of the remaining bulbs.

For small battery powered circuit, yes removing one light from a parallel circuit would cause the others to burn brighter.
The current is divided equally between all 4 light bulbs, when one is removed, the other three will have more current and will burn brighter.

ok, so...since the light bulb filaments are not wired together, meaning they are all seperate and only connected by the power source (im assuming they aren't) the removal of one light bulb WILL NOT effect the brightness of the other three. The only thing that will happen is that the power source will not have to feed more energy to light the fourth light bulb.
:) GOOD LUCK on your test!

In a parallel circuit the same voltage is applied to all . If the brightness did increase your supply is over loaded. If u have a good power supply u would be able to put them all in or out without affecting the others.

if running off a battery with constant voltage shouldn't, cause voltage is constant, like the light bulbs in ur house, if one is removed does not affect the brightness of others

Say battery A is a 100V battery and that that is related to a a hundred ohm resistance. Then that is giving out precisely a million ampere of modern-day (I=V/R). Remembering that P= I^2xr, then P=a million^2x100 =a hundred Watts Then, if Battery B is likewise a 100v battery and that is related to a 50 ohm resistance, then it would be giving out 2 amperes of modern-day. Then with the aid of a similar calculation it would be producing 200 Watts of capability. so user-friendly as that.
