in an ac series circuit there are 30 bulbs are connected in
a serial set.what will happen if one bulb is fused and we
removed the bulb and reconnect with the remaining bulbs? (29
bulbs). will the brightness of other bulbs increase or not?

Answer Posted / satheesh

The applied voltage divided by the total series resistance is the current passing through the bulbs since it is in series.When one bulb is fused there is a reduction in resistance and prorate increase in current.so corresponding increase in brightness definitely be there.
