A 100 W bulb offers less resistance to electric current than a 25 W bulb' - justify the statement.

Text Solution

Verified by Experts

A 100 W bulb is one which utilizes more energy in unit time compared to that of a 25 W bulb.
A wire which offers more electric resistance liberates more heat energy.
The current through a wire of less resistance is more than that in a wire of higher resistance.

Which one is having more resistance,100 W bulb or a 50 W bulb?

Two bulbs of 100 W and 40 W are connected in series. The current through the 100 W bulb is 1 A. the current through the 40 W bulb will be:

Assertion (A): When two bulbs are operated on same voltage supply, having power 60 W and 100 W then 100 W bulb has less resistance than 60 W. Reason (R): The power of the bulb is directly proportional to the square of the voltage.

(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.

Two bulbs of 100 W and 40 W are connected in series. The current through the 100 W bulb is 1 A. The current through the 40 W bulb will be:

Statement-1: Two bulbs of 25 W and 100 W rated at 200 V are connected in series across 200 V supply. Ratio of powers of both the bulb in series is 2:1 Statement-2: In series current in both bulbs is same, therefore power depends on resistance of bulb.

When a 100 W, 240 V bulb is operated at 200 volt, the current in it is -

Which has more resistance : 100 W bulb or 60 W bulb ?
