Homework Help: Input and Output graphs with capacitor

    1. The problem statement, all variables and given/known data

    Hello all, there has been some debate in my class as to the output waveform for the following circuit:

    Others say that the output will always be zero.

    I forgot to say that I am really looking for someone to say whether the output in the graph is right, or if it would indeed be zero.

    The output won't be always zero. How closely the output resembles what you've drawn will depend upon the frequency with which the input signal alternates from + to - and back, compared to the circuit's RC time constant.

    The other individuals argued that since the ground is connected near the bottom of the resistor, the output voltage, which is in the far right corner, would always be zero.

    That's not an argument, it's an unfounded assertion :smile:
