Answer» A resistor–capacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors driven by a voltage or current source. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit. RC CIRCUITS can be used to filter a signal by blocking certain frequencies and PASSING others. The two most common RC FILTERS are the high-pass filters and low-pass filters; band-pass filters and band-stop filters usually require RLC filters, though CRUDE ones can be made with RC filters.The simplest RC circuit is a capacitor and a resistor in parallel. When a circuit consists of only a charged capacitor and a resistor, the capacitor will discharge its stored energy through the resistor. The voltage across the capacitor, which is time DEPENDENT, can be found by using Kirchhoff's current law, where the current discharging the capacitor must equal the current through the resistor. This results in the linear differential equation Explanation:
