🔍 Key Concepts

• Sinusoidal wave shape and how it looks on a voltage (V) vs. time (t) graph • Differences between smooth, continuously curving waves and sharp-cornered (square, sawtooth, triangular) waves • The idea that a sine wave has no flat tops and no straight sloping sides—it is all smooth curve

💭 Think About

• Looking at each option, which waveform has a smooth, rounded rise and fall rather than straight lines or flat levels? • Which options show sharp corners, sudden jumps, or straight ramps in voltage—are those consistent with a true sine (sinusoidal) wave? • On an AC power diagram, what does the basic ideal alternating current or single-phase generator output typically look like?

✅ Before You Answer

• Eliminate any waveforms with flat horizontal sections (these are more like square or rectangular waves). • Eliminate any waveforms made from only straight, slanted lines that form triangles or sawteeth. • Select the waveform that is continuously curved and symmetrical above and below the center (zero) line.
