In a power system, the voltage and currents for a Y-connected load are given asV(t)=220cos(ωt-20°)I(t)=110sin(ωt +30°)What is the load impedance in each phase?
Question
Solution 1
To find the load impedance in each phase, we need to use Ohm's law, which states that the impedance (Z) is equal to the voltage (V) divided by the current (I).
Given that the voltage V(t) = 220cos(ωt-20°) and the current I(t) = 110sin(ωt +30°), we can find the magnitude and phase angle of each.
