🔍 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

Current is in phase with the applied voltage.

Current leads the applied voltage by 90 degrees.

Current lags the applied voltage by 90 degrees.

Current lags the applied voltage by 180 degrees.
