Two bulbs have ratings 100 W, 220 V and 60 W, 220 V. Which one has a greater resistance ?

Two bulbs of (40W 200V) and (100W 200V). Then correct relation for their resistances:

A and B are two electric bulbs with their ratings respectively 40 W, 110 V and 100 W and 110 V. Find their respective filament resistances. If the bulbs are connected in series with a supply of 220 V, which bulb will fuse ?

An electric heater and an electric bulb are rated 500W. 220V and 100W, 220V respectively. Both are connected in series to a 220V d.c. mains. Calculate the power consumed by (i) the heater ana (ii) electric bulb.

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

A light bulb is rated at 100W for a 220 V supply. Find (a) the resistance of the bulb, (b) the peak voltage of the source, and (c) the rms current through the bulb.

An electric iron consumes energy at a rate of 840 W, when heating is at the maximum rate and 360 W, when heating is atthe minimum. The voltage is 220V. What are the current and the resistance in each case?

Assertion: The 200 W bulb glows with more brightness than 100W bulbs. Reason: A 100W bulb has more resistance than a 200W bulb.
