Hello all, quick question. I'm experimenting with simple RC circuits in hopes to eventually make a simple timer. I have connected the following 5vdc -> 1MΩ -> +electrolytic cap(1uf) -electrolytic cap -> ground(5vdc return).
Just a simple RC circuit. My issue is the display on the scope, it appears that the capacitor only charges to approximately 2.5 volts. I know it will never charge to a full 5v but after 5 time constants(5 seconds in this case) it should approach 4.7 volts. Is the "loading" effect of the oscilloscope causing this issue? If so is there a way to correct it? My DMM reads the correct voltage.
Not sure if this is the best way to test the scope, but I connected the 5v directly and it reads perfectly
Thanks for the help ahead of time.
