Delta transformation circuit
1. The problem statement, all variables and given/known data
Above is the picture of the circuit i'm trying to solve. The problem asks to find the current over the resistor of 1 ohm.
2. Relevant equations
3. The attempt at a solution
Well, I found the equivalent resistence of the circuit and thus the total current. But to do this, I transformed the T-form of the circuit between the resistors 70,1 and 20 ohms in a delta-transformation. My doubt is when I know the current in each branch of the delta-form how am I suppose to find the current in each branch of the t-form? What is the relation of current between them?

Welcome to the PF, danilo. Wouldn't it be easier to just solve the circuit using Kirchoff's Current Law (KCL) equations? That would be my first approach.

That's a nice idea, I haven't thought that. Well, I found the current over the resistor of 1 ohm as being I = 0.1904 A. I would appreciate If you could check this answer for me.
