Two lamps, one rated 220 V, 50 W and the other rated 220 V, 100 W, are connected in series with mains of voltage 220 V. Explain why does the 50 W lamp consume more power.

Two identical heaters rated 220 V , 1000 W are paced in series with each other across 220 V line , then the combined power is

Two lamps, one rated 100 W at 220 V , and the other 60 W at 220 V , are connected in parallel to the electric mains supply. What current is drawn from the line if the supply voltage is 220 V ?

If two bulbs of power 60 W and 100 W respectively each rated 110 V are connected in series with the supply of 220 V, then

Two lamps, one rated 40 W at 220 V and the other 100 W at 220 V, are connected in parallel to the electric supply at 220V. (a) Draw a circuit diagram to show the connections. (b) Calculate the current drawn from the electric supply. (c) Calculate the total energy consumed by the two lamps together when they operate for one hour.

If two bulbs, both of rated power 100 W at 220 V, are connected in series with a 220 V supply, the total power consumed by the bulbs will be:

Two bulbs of rated power 60W and 100W same specified voltage 220 V are connected in series to a 440 V DC source

Two lamps, one rated 40 W, 220 V and the other having resistance of 605 Omega and rated 60 W, 220 V are connected in parallel combination across a 220 V supply. Calculate the current drawn from the supply line.

An electric bulb is rated "220 V, 100 W'. What is its resistance ?

60W-220V and 100W-220V bulbs are connected in series to 220V mains. The power consumption is more in the bulb of :

Two bulbs are marked 220 V, 100 W and 220 V, 50W respectively. They are connected in series to 220 V mains. Find the ratio of heats generated in them.
