Question

The period of a given sinusoidal a.c. waveform is 0.005s, which of the following best represents that waveform?
Options
A v = V sin 1257ωt
B v = V sin 0.005 ω
C v = V sin 1257t
Correct Answer
D v = V cos ωt
Correct Answer

Option C is the correct answer.

Detailed Explanation

ω = 2π/T = 2π/0.005 = 1256.6 rad/s ≈ 1257. So v = V sin(1257t).

Hint

ω = 2π/T. Compute ω.
