AI Thread Summary
To find the current through resistor R1 in a parallel circuit with a total current of 4.06A, the voltage across R1 must first be determined. The relationship I = V/R can be applied once the voltage is known. Transforming the circuit from delta to star can simplify the analysis and help in calculating the equivalent resistance. Understanding circuit analysis techniques is crucial for solving this problem effectively. Utilizing these methods will lead to the correct determination of IR1.

I already got the total current that I did doing the Delta / star . what I got is 4.06 for total current, now is asking me to get the current of R1 , I know I have to get the voltage in order to get the current that is I = V/R but I don't have any idea how to get the voltage when is parallel I am lost somebody can help me please! :(

What circuit analysis techniques are have you been introduced to?
 
You can determine IR1 by using equivalent ciruit after u transform delta-->star

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
