Engineering Parallel Circuit Voltage Calculation: Solving for Voltages using Ohm's Law

AI Thread Summary
In a parallel circuit, the voltage across each component is the same, and the total current is the sum of the currents through each resistor. The discussion emphasizes the importance of clear problem statements for effective assistance. The user initially attempted to calculate voltage by multiplying current and resistance but was prompted to consider other current sources in the circuit. After further calculations, the user concluded that the voltage is 4.8V and the current through the 3-ohm resistor is 1.6A, receiving confirmation that their solution is correct. The conversation highlights the necessity of understanding circuit principles and the application of Ohm's Law in solving for voltages.

Homework Statement


Solve the next circuit to find the voltages

Homework Equations


I=V/R
GT=(1/R1)+(1/Rn)
V=V1=V2=V3

The Attempt at a Solution


My background is that I know that in a parallel circuit, the voltage for each component is the same and electric current it's equal to the sum of the electric currents of each one of the resistances by separate. My first and only attempt was to multiply the 5A by 3 ohms.

Your problem statement is not clear or complete. What do you mean by "Solve the next circuit"? Solve for what? Please make an effort to provide clear problem statements that can be readily understood by the Homework Helpers.

What was your motivation for multiplying 5A by 3 Ohms? What about the 1A source and the other resistor?

Hint: You are given a current through one of the resistors. Does that give you any useful voltage information?

According what I understand, the 2.4A would help me to get the voltage using Voltage=(current)(resistance), or in what way can it help me?

I made a procedure and I get that the voltage=4.8V and the current for the resistance of 3 Ohms it´s equal to 1.6A, am I right?
