Ac Through Resistor Inductor And Capacitor. This lecture is about summery ofa ac through resistorb ac through capacitorc ac through inductord impedance. The phase difference is 90 degrees it is customary to use the angle by which the voltage leads the current.
Ac through inductor capacitor and resistor. March 21 2017 by admin. Basic electrical components resistor capacitor and inductor.
Resistor capacitor and inductor in the following we adopt the convention that a constant or direct current dc or voltage is represented by an upper case letter or while a time varying or alternating current ac current or voltage is represented by a lower case letter or sometimes simply and.
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. The voltage drop across the resistor is vr i r this is in phase with i. 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. 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.
