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

Options

A. If both assertion and reason are ture and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If assertion and reason both are false.

Answer

A

Explanation

(a) The resistance, `R = (V^(2))/(P) implies R prop 1//P`
i.e., higher is the wattage of a bulb, lesser is the resistance and so it will glow bright.
