The voltage of the domestic electric supply is represented by the equation V = 311 sin314.2t. Determine the frequency of the a.c. supply [\(\pi\) = 3.142]
-
A.
50.0Hz
-
B.
100.0Hz
-
C.
311.0Hz
-
D.
314.2Hz
Correct Answer: Option A
Explanation
V = 311 sin314.2t compare with,
V = V sin2\(\pi\)Ft
2\(\mu\)F = 314.2
F = \(\frac{314.2}{2 \times\ 3.142}\)
F = 50Hz
