WebA resistor and a capacitor can be combined to make an AC current divider or filter circuit. When the frequency is low, the impedance of the capacitor is high, so most current will flow through the resistor. As the frequency increases, more current is diverted through the capacitor, less to the rest of the circuit. Thus, the response is low pass. http://www.learningaboutelectronics.com/Articles/How-to-calculate-the-current-through-a-capacitor the home theater store in russellville
