Ac Through Resistor Inductor And Capacitor. The magnitude of this opposing response or force of an inductor to an ac or alternating current is called the reactance of the inductor. Just as the current through a resistor is a function of the voltage across the resistor and the resistance offered by the resistor the ac current through a capacitor is a function of the ac voltage across it and the reactance offered by the capacitor.
Resistor inductor and capacitor in series let an alternating source of emf e be connected to a series combination of a resistor of resistance r inductor of inductance l and a capacitor of capacitance c fig 4 21a. March 21 2017 by admin. Basic electrical components resistor capacitor and inductor.
Let e be the rms value of applied emf and i be the rms value of the current flowing in the circuit.
The voltage drop across the resistor is vr i r this is in phase with i. Suppose a current i is flowing through an inductor of inductance l then. When the electrons move through resistor they collide with the atoms of the resistor and this affect the speed of electrons. Inductor with capacitor an inductor will basically behave and produce a short across itself when subjected to a dc while offer an opposing or restricting response when applied with an ac.
