Assertion : The electric bulbs glows immediately when switch is on.
Reason : The drift velocity of electrons in a metallic wire is vary high.

A

If both the assertion and reason are true and reason is a true explanation of the assertion.

B

If both the assertion and reason are true but the reason is not the correct explanation of assertion.

C

If the assertion and reason are false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) As the conductor is foil of electrons, with slight drift anywhere the queue starts moving. As a reusult bulb starts glowing instantly. Drift velocity of electrons in a good conductor is very low.
