The three basic properties of AC voltage are.

• A. Phase, Resistance, Capacitance
• B. Wavelength, Velocity, Modulus
• C. Period or Time, Frequency, Amplitude
• D. Power, Energy, Impedance

Answer: (C)

AC voltage is a time-varying signal described by how tall the peaks are and how the waveform repeats in time. The fundamental properties here are amplitude (the maximum voltage), the period (the time for one complete cycle), and the frequency (how many cycles occur each second). The period and frequency are inverses of each other, T = 1/f, and the waveform can be expressed as v(t) = Vp sin(ωt) with ω = 2πf. The other options mix quantities that aren’t intrinsic to the basic waveform itself—like circuit elements (resistance, capacitance, impedance) or quantities tied to energy or space (power, energy, wavelength, velocity). So the trio of period, frequency, and amplitude best captures the essential characteristics of an AC voltage.
