Hello
For some reason I have such a difficult time understanding how this works. I am aware of how to do the calculations for a time constant. I also know that a capacitor has an reactans XC which act as a resistor, and that at higher frequenzs the reactans will drop.
Questions:
Does a capacitor at a low frequenze have a longer time to charge? And how does this affect the capacitor and the reactans?
I dont get why it has to be ac and not dc. What if I had a frequnze of DC square waves?
