Assertion: Zener diode works on aa principle of of breakdown voltage. Reason: Current increases suddenly after breakdown voltage.A. If both the assertion and reason are true and reason is a true explantion of the assertion.B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.C. If the assertion is true but reason falseD. If both the assertion and reason are false.

Answer» Correct Answer - A
