If bulb rating is 100 walt and 220 V then determine
(a) Resistance of filament
(b) Current through filament
(c ) If bulb operate at 110 volt power supply then find consumed by bulb.

(a) A 220V-100W bulb is connected to 110V source. Calculate the power consumed by the blub. (b) Calculate the following for a 100W - 200V bulb (i) Resistance of the filament of bulb (ii) Current through bulb when it is connected to 200V line (iii) Power consumed when bulb is connected to 100V line (c) An electric bulb rated 100W -200V is used in a circuit having 400V supply. what resistance R must be put in series with bulb so that bulb delivers 100W ? (d) Repeat the previous problem, if bulb delivers 25W . (e) Two bulbs, 50W-220V, 100W-200V are connected in series across a 220V supply. find the power consumed by each bulb.

An electric bulb is rated 60 W , 220 V . The resistance of its filament is

A light bulb has the rating 200W 220V. Find (i) resistance of the bulb filament (ii) rms value of current flowing through the filament.
