We got the resistances of star network from delta network as Equation 1
Equation 2
Equation 3
Delta Network Resistances in terms of Star Network Resistances
Let us manipulate the above equations in order to get the resistances of delta network in terms of resistances of star network.
By using the above relations, we can find the resistances of delta network from the resistances of star network. In this way, we can convert star network into delta network.
Example
Let us calculate the resistances of delta network, which are equivalent to that of star network as shown in the following figure.
Given the resistances of star network as RA = 6 Ω, RB = 18 Ω and RC = 3 Ω.
We know the following relations of the resistances of delta network in terms of resistances of star network.
Substitute the values of RA, RB and RC in the above equations.
So, we got the resistances of delta network as R1 = 10 Ω, R2 = 60 Ω and R3 = 30 Ω, which are equivalent to the resistances of the given star network.
