Current and voltage in an AC resistive circuit are ? phase. Current and voltage in an AC resistive circuit are ? phase . in Factors such as skin effect and eddy currents are present in an AC circuit and in practice ? the resistance of the conductor . In a pure ohmic AC Resistance the current and voltage are both “in-phase” as there is no phase difference between them. The current flowing through the resistance is directly proportional to the voltage across it with this linear relationship in an AC circuit being called Impedance. When capacitors or inductors are involved in an AC circuit the current and voltage do not peak at the same time. The fraction of a period difference between the peaks expressed in degrees is said to be the phase difference . The phase difference is < = 90 degrees . It is customary to use the angle by which the voltage leads the current . From equation (1) and (3) it is clear that there is no phase difference between applied voltage and the current flowing through a purely resistive circuit the i. e . phase angle between voltage and current is zero . Hence in an AC circuit containing pure resistance current is in phase with the voltage as shown in the waveform figure below. For a capacitive load the current in an AC circuit leads the voltage by π/2 ( 90 o) phase . In a real electrical circuit there is a mix of resistive capacitive and inductive loads with a...
