Q1:

Assertion (A): Snubber circuit has an RC series circuit in parallel with SCR Reason (R): Voltage across a capacitor can not change instantaneously.

A Both A and R are correct and R is correct explanation of A

B Both A and R correct but R is not correct explanation of A

C A is correct but R is wrong

D A is wrong but R is correct

ANS:A - Both A and R are correct and R is correct explanation of A
