Alternating current wave prob

[Rasine]

alternating current wave prob...

assume the wave is sinusoidal. suppose that each horizontal division (13) represents 1.0 ns and that each vertical division (11) represents 1 mV. what is the approx. rms voltage?

please help me solve this.

i am not so sure how to find rms, and if you do please explain it.

thank you.

Look at the example for RMS current.

Were you trying to post some waveform? 11/13/etc. Whatever. If you want the RMS, just use the Vpp measurement to get you there. Vp= sqrt(2)*Vrms, Vpp = 2*sqrt(2)(Vrms)


EDIT -- If you want a more complete explanation of RMS versus Vpp, we can oblige.

what is the Vp measurement? and how does it related to rms?
