Question 1 Report

The voltage of the domestic electric supply is represented by the equation V = 311 sin314.2t. Determine the frequency of the a.c. supply [ $π$ = 3.142]

50.0Hz

100.0Hz

311.0Hz

314.2Hz

Answer Details

V = 311 sin314.2t compare with,

V = V sin2 $π$ Ft

2 $μ$ F = 314.2

F = $\frac{314.2}{2 \times 3.142}$

F = 50Hz
