Out of 60W and 40W kamps, which has electrical resistance when in use. Explain |
| Answer» Let us assume that the two bulbs are connected to the same supply. Let us say the value of the supply is voltage V. Now for 40 W bulbResistance of 40W bulb = V*V/40SimilarlyResistance of 60W bulb = V*V/60Since the denominator of first is less, hence the Resistance of 40 W bulb will be MORE than the resistance of 60W bulb. | |
