🔍 Key Concepts

• Figure C shows a purely resistive AC circuit with element R only • In a resistor, voltage and current waveforms reach their zero crossings and peaks at specific relative times • Compare the IR (current through the resistor) waveform with the total voltage VT waveform in Figure D

💭 Think About

• Look at the IR curve and the VT curve in Figure D: do their peaks and zero crossings occur at the same time, or does one occur earlier? • At 90°, 180°, 270°, etc., how do the IR and VT values compare—are they both positive/negative together, or is one positive while the other is negative? • In a purely resistive circuit, does the resistor store energy like a capacitor or inductor, or does it simply dissipate it, and how does that affect phase shift?

✅ Before You Answer

• Verify on the graph whether IR and VT cross the zero axis at exactly the same instants • Check whether the maximums and minimums of IR line up horizontally with those of VT • Confirm that in Figure C there is only R (no L or C), indicating a purely resistive circuit with no reactive phase shift
