Question
Referring to the Figure 2 below, set the value of voltage Vs as: -
Vs (rms) = (220+the last 2 digit ID Number) 290° V
Example: ID No : RE20630; So, Vs (rms) = (220+30)/90° V
Vs (rms) = 250/90° V
Then, determine: -
i)
The complex power of each load; Load 1, Load 2, Load 3 and Load 4.
ii)
The total complex power delivered to the loads.
iii)
The overall power factor and state either lagging or leading.
iv)
The current supplied by the source, IT
v)
The value of the capacitance connected in parallel that will raise to the power
factor unity
(Write your answer in 3 decimal places.)
