<b>Assertion (A):</b> A bulb glows only when the electric circuit is complete. <b>Reason (R):</b> Electric current flows only through a closed circuit.
Options
Option A is correct
A. Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
Option B
B. Both Assertion and Reason are true, but Reason is not the correct explanation.
Option C
C. Assertion is true, but Reason is false.
Option D
D. Assertion is false, but Reason is true.
Explanation
For a bulb to glow, electric current must flow through it. Current only flows when there is a complete, unbroken path, which is a closed circuit. Therefore, the reason correctly explains the assertion.
