Homework Statement
Based on Fig. 4,
Z_{Δ}=6+8j Ω
Z_{Y}=4+3j Ω
E_{L}=200V
Show that the equivalent deltaconnected load is 7.846  2.77j
Homework Equations
Z_{Y}=(1/3)Z_{Δ}
The Attempt at a Solution
Here's my thought process:
For part (i), attempt to convert Y to Δ,
So using the relevant equation above
Z_{Δ} of transformed Z_{Y} is 12 + 9i
However, that's not done because I need to combine the two delta loads.
Hence, I use the product/sum rule to obtain the combined delta:
((12+9i)(6+8j))/((12+9i)+(6+8j))
which obtained 4.1598 + 4.405j which is wrong
I also used https://www.physicsforums.com/threads/deltaandstartransformationaccircuits.791979/ as guidance for this problem but can't quite point out where my mistake is.
