Assertion (A): Two bulbs A and B are rated as 100W,220V, and 40W,220V respectively. Resistance of bulb A is more than that of bulb B. Reason (R ): For a given potential difference the power consumed in a resistor is inversely proportional to its resistance.

1.	Assertion (A): Two bulbs A and B are rated as 100W,220V, and 40W,220V respectively. Resistance of bulb A is more than that of bulb B. Reason (R ): For a given potential difference the power consumed in a resistor is inversely proportional to its resistance.
Answer» Both (A) and (R ) are true and (R ) is correct explanation of the assertion Both (A ) and ( R) are true but (R ) is not the correct explanation of the assertion. (A ) is true but (R ) is FALSE (A) is false but (R ) is true Solution :Assertion is wrong but reason is true. Resistance of 40W BLUB is more than that of 100W bulb because for POWER `P=V^2/R`
