_0000065248.png "The image illustrates the behavior of electrical signals in a purely resistive circuit. It features two sinusoidal waveforms—voltage (V) shown as a solid blue line and current (I) as a dashed green line—both having the same frequency and phase alignment. The horizontal axis represents time, with key phase markers at 90° and 270°. A resistor symbol is placed between the V and I labels to indicate the resistive nature of the circuit. On the right side, a phasor diagram displays voltage vectors (Va, Vb, Vc) and current vectors (Ia, Ib, Ic), all aligned to show that voltage and current are in phase.")
_0000065247.png "The image illustrates the phase relationship between voltage and current in a capacitive circuit. On the left, a graph displays two sinusoidal waveforms: voltage (V) in blue and current (I) in green. The current waveform leads the voltage waveform by 90 degrees, indicating a capacitive load. On the right, a phasor diagram shows voltage vectors Va, Vb, Vc and current vectors Ia, Ib, Ic, representing the phase angles and magnitudes of each phase in a three-phase system.")
_0000065246.png "The image illustrates the phase relationship in an inductive circuit. On the left, two sinusoidal waveforms are shown: voltage (V) in blue and current (I) in green. The current waveform lags the voltage waveform by 90 degrees, indicating inductive behavior. On the right, a phasor diagram displays voltage vectors (Va, Vb, Vc) and current vectors (Ia, Ib, Ic), representing the phase angles and magnitudes of each phase in a three-phase system.")
