Today in my electronics class, we were introduced to the amp op concept. After going through some fundamentals, the teacher challanged us to find v0 of a simple circuit with a battery and two resistances of 1M ohm each(v0 is in between these resistances). Afterwards he asked us if this same value would be correctly read by an oscilloscope. The answer would be no because of the internal resistance of the oscilloscope (1M ohm) that would then be parallel with one of the resistances from the circuit.
One of my classmates then asked why wasn't there a buffer incorporated on the oscilloscope.
I went home and looked out what a buffer would do and realized that my classmate's question made a lot of sense. I tried to look up if buffer was high energy consuming or if it could short circuit both the oscilloscope and our circuit but with no success. Or maybe sometimes we want to module our wave through some options from the oscilloscope itself and using a buffer might complicate that. So my question is: why is this?
Thanks
