  • 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.

    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.

  • Assertion : Two electric bulbs of 50 and 100 W are given. When connected in series 50 W bulb glows more but When connected parallel 100 W bulb glows more . Reason : In series combination, power is direclty proportional to the resistance of circuit. But in parallel combination, power is inversely proportional to the resistance of the circuit.

    A
