I took some measurements for a Physics lab and don't recall whether the Voltmeter I used reports the peak voltage or rms voltage. I need rms voltage to calculate the rms current. Can anyone tell me what the norm is for voltmeters: peak or rms?
To divide by the [squ]2 or not to divide by the...
While working on an infinite barrier problem I was surprised to find that the location of |psi|^2 = 0.30 a while <x> is 0.32 a, where a is the width of the well.
It's often said that |psi|^2 tells one about the probabilty of finding a particle in a location x. Yet the expectation of x, <x>...
