Its seems complicated to see a circuit which you don't know where is the series connection and parallel connection is. But don't worry,Wye-Delta and Delta-Wye Transformation is to the rescue. Wye-delta Transformation is already discussed in our lesson four blog but here we will give some examples and we will explain slowly, step-by-step.
Example 1:
Find Rab and i.
Find Rab and i.
In this example, there are two Y-networks comprising the first Y-network (24Ω, 30Ω, and 30Ω) and the second Y-network (10Ω, 50Ω and 30Ω). You can use both to find the Rab and i ...But in this example we will use the second Y-network.
Example 2:
Transform the circuit from delta to Y
Transform the circuit from delta to Y
Example 2 is an example of a delta-network. We are going to transform it into Y-network.
Question? : Why we need to transform the circuit from Y to delta or from delta to Y?
Answer: to get the series and parallel equivalent of the resistance in the circuit.
