Hi,

I am working with capacitor now and I have this question. I am applying a square wave (from 0 to 5V) on a RC circuit.

At the output ( at the resistor) I get a positive and negative values? why is that ?

I am suspecting the fact that the capacitor create a phase difference of -90 degree(between voltage and current)..but I cannot figure out the correct answer.

please can someone help me?
