I can't really send it back it's a question in a final year exam. Someone helped me out by sayingThe question is ambiguous.
The definition of rms voltage is the DC voltage that produces the same power.
Is it 20VDC (rms) or 20VAC (rms)? Send it back to your instructor.
no one did :/Who said it was a sinewave?
Assuming it's a sinewave (and you would need to state that in your answer) why would you go with 18.6 if you think it's half-wave rectified?Should I go with that or the 18.6 I previously had.
First year electronics in university.The answer depends on the shape of the input waveform.
Let us assume that who wrote the question intended it to be a sinewave centered about 0V.
Then it becomes a trick question.
What level course is this?
Someone I had asked on another forum solved it as a half wave rectified. I do not know what wave form it is, it does not say. But since it is rms I assume sine wave? I am new to electronics this is a first year exam.Assuming it's a sinewave (and you would need to state that in your answer) why would you go with 18.6 if you think it's half-wave rectified?
If you think the question is ambiguous, simply state your assumptions with your answer.I can't really send it back it's a question in a final year exam.
