प्रश्न

The resistance of 100 W (220 V) bulb is greater than that of 60 W (220 V) bulb. Is it true or false?
संख्यात्मक

उत्तर

We know that, R = `"V"^2/"P"`

Thus, voltage remaining constant, resistance is inversely proportional to the power of the appliance; which means resistance of 60 W (220V) bulb is greater.
Hence, the given statement is false.
