i have carried out an experiment on characteristic of the sine wave voltage.i have record the value of the peak voltage.the rest value such as vrms,irms,radian frequency can be calculated.i was confused on what should i write on discussion part in the lab report.can someone help me?

dunno whats expected of you by your prof. but, you could always discuss the practical applications of being able to determine Vpk when given rms values. For example, when computing what shielding is to be used in radio transmission lines, you must determine the peak to peak values and choose a shielding that will contain the voltages above the rms so as not to have leakage into other rf sensitive devices. Or you may discuss how in AC power generation, only the rms value is usable because the voltage above this level is so out of phase with the current that it becomes unusable in most modern devices which is why the 120VAC power that we get from an ordinary household receptacle is actually on the order of about 169VAC peak. which, as im sure you know being the bright MIT student that you are can be derived from taking the rms value divided by .707 which is the square root of the averages of the squares of all the instantaneous voltages along the 360deg. of the sine wave. also, Vpk times sine of theta. which is the angle. again, i dont know what the prof. wants you to discuss but, these are a couple of practical applications of the theory. I hope my rambling garble was helpful.
