🔍 Key Concepts

• AC + DC composite waveforms and how an AC component affects the average value over a full cycle • The fact that a pure sinusoidal AC voltage has an average value of zero over a complete cycle • Using Ohm’s Law ( I_{avg} = \frac{V_{avg}}{R} ) with the DC (average) level shown on the waveform

💭 Think About

• Look carefully at figure B: what horizontal dashed line is drawn through the waveform, and what voltage value does it represent? • If the AC portion of the voltage swings equally above and below that dashed line, what will its average contribution be over one full cycle? • Once you know the average (DC) voltage across a 1‑ohm resistor, what does Ohm’s Law tell you about the average current?

✅ Before You Answer

• Identify the DC level (steady value) of the composite waveform in figure B from the dashed reference line • Confirm that the AC variation is symmetrical above and below that DC level, meaning its average over a full cycle is zero • Apply Ohm’s Law with (R = 1,\Omega) using only the average (DC) voltage to compute the average current
