Why add sub tree of (9,4,5) on 9 located on left node instead of right node's 9? (HUFFMAN ALGORITHM EXAMPLE QUESTION)
posted in Tree - Part 3In case of sub-tree (3,1,2), we added that tree to the 3 located on right node of root 6. However, in case of sub-tree (9,4,5), we added that tree to the 9 located on left node of root 18. Why didn't we add the sub-tree to the right node ... -
Why -E1 in $V1=I0*R1+I0*XL1-E1$?
posted in Practical TransformersHello, Please could you explain why there is a term -E1 on the L0 R0 branch of the practical transformer, but the term +E applies to the primary winding? Due to KVL, the voltage at the node where these three components meet should... -

At time 35:10 when finding the expression for the power in phase 2, why does the teacher replace "wt" with "wt-180" and not replace the angle "phi" with "phi-180"? wplease clarify
posted in 3 Phase Star-Star SystemAt time 35:10 when finding the expression for the power in phase 2, why does the teacher replace "wt" with "wt-180"? I thought you would have to replace "phI" with "phi-120"! Please explain!... -
The expression for power
posted in 3 Phase Star-Star SystemIn this video, and before it, the teacher states power as: P=V*I For an AC circuit, it will then be: P=Vcos(wt)*Icos(wt-phi) Now from here the teacher does a simplification or changes it using a trig identities I believe, so... -
