Connection Of Bulbs In Series

Some electric bulbs are connected in series across a 220 V supply in a room. If one bulb is fused then remaining bulbs are connected again in series across the same supply. The illumination in the room will

40 electric bulb are connected in series across a 220 V supply. After one bulb is fused the remaining 39 are connected again in series across the same supply. The illumination will be

A bulb B a capacitor C are connected in series to an a.c. source. A dielectric slab is now introduced between the plates of the capacitor. How will the brightness of bulb change ?

Two bulbs are rated 30 W - 200 V and 60 W - 200 V . They are connected with a 400 V power supply. Find which bulb will get fused if they are connected in (i) series and (ii) parallel.

Two bulbs one of 200 volts , 60 watts & the other of 200 volts , 100 watts are connected in series to a 200 volt supply . The power consumed will be Assume the light bulbs are rated for single connection to 120 V. With the mistaken connection , the power dissipated by each bulb is

When bulbs are connected to the same source, the brightness of bulb connected in parallel is "________" then the brightness of identical bulbs connected in series.
