hello everyone! i was solving these MCQz related to AC fundamentals... the book is from an Indian writer. i solved a few but was surprised to see that my answers did not match the options. so i'm confused whether my answers are wrong or is it the book. If any one can solve these for me i'd appreciate it a lot. thanks.

For the first picture multiply the RMS value by sqrt2 to find the instantaneous value.

For picture 2, your answer about the instantaneous power is correct.

For picture 3, you are right.
