Final answer:
To find the value of y₀, use source transformation to convert the circuit into a current source and parallel resistors. Then, find the current flowing through the resistor and the voltage across it to obtain y₀.
Step-by-step explanation:
To find the value of y0, we need to use source transformation. Firstly, let's convert the voltage source and the series resistors (3Ω and 2Ω) into a current source and parallel resistors. The resulting circuit would have a current source of 3A, a resistor of 3Ω in parallel with a resistor of 2Ω, and a resistor of 6Ω in parallel with the combination of the 3Ω and 2Ω resistors. Next, we can combine the 3Ω and 2Ω resistors into a single resistor of 5Ω using the formula for resistors in parallel. Finally, we can find the current flowing through the 5Ω resistor using Ohm's law, and the voltage across that resistor will be the value of y0.
