Hi
Sorry for the beginner's level question, but I would be grateful if someone could explain.
I am playing around with RC circuits. I am using an oscilloscope to display the AC waveform across the resistor/capacitor in series. I do not understand why it will only display a waveform when I attach the probe and earth one way, i.e. when i swap the probe and earth lead around no voltage is shown. I expected to see a voltage no whatever way I connected the probe and earth across the circuit because it an AC waveform.
Can someone please explain this basic concept? I really appreciate your help.
Many Thanks
Mac
