R1 and for the non inverting amplifier the multiplication constant is the gain r2. A resistor is an electrical device which has a property to oppose the flow of electric current through it. The main function of a resistor within an electrical or electronic circuit is to oppose or resist the flow of current, hence named as resistor. When the frequency is low, the impedance of the capacitor is high, so most current will flow through the resistor.
Basic electrical components resistor, capacitor and inductor. In a practical capacitor, some part of the current passing through the capacitor is dissipated because there is a small amount of resistance to the flow of current.
