Could somebody assist me with a circuits lab?
I'm taking a AC circuits lab at my school and my teacher asked us the following questions, could someone help me answer them?
1. Does a digital multimeter record true RMS values for all frequencies and waveforms?
2. How do the RMS values for a sine, square, and triangle wave differ?
3. Which instrument provieds a more accurate measurement for the period of a wave, a frequency meter or an oscilloscope? Why?
Ahhh come on guys, my lab report is due monday and I have to answer these questions in it. And we dont have a textbook for lab... and I am not even an engineering major, I major in biology and am just trying to get a physics minor because it looks good for med school. Can anyone help me, I am at a real crossroads here.....PLEASE!!!!!
Exercise your brain & not your fingers (keyboard). You will benefit greatly if you make an effort to do this yourself - just like I did for 8 years.
I hate to imagine the quality of the next generation of engineers - all of them will end up going to Yahoo Answers.
