in a series circuit, as light builbs are added, the current at the battery increases/decreases, remains the same.

anonymous · Answer

Voltage at battery remains the same, but the current decreases. Addiing lightbulb increases the total resistance of the circuit, hence decreases current.

anonymous · Answer

so in a parallel circuit, voltage would be the same, and current would increase because of decrease in resistance?

anonymous · Answer

Yes,

anonymous · Answer

but i thought if a light bulb were removed/added, its brightness wouldn't change

anonymous · Answer

in parallel

anonymous · Answer

You could try if you want :)
Which part makes you think like that.

nvm you're right, thanks!
