I am new to using oscilloscopes. When I was consistently getting zero voltage in an experiment I was doing, I decided to test whether my oscilloscope was working properly.
I set up a very simple circuit consisting of only a power supply at 3 volts and a resistor. However, the measurement on the oscilloscope of the voltage drop across the resistor remains jittering around zero.
Increasing the voltage causes a brief increase in the reading before it falls back down to zero. Is there something I am doing wrong or is the oscilloscope faulty?
