I need to find the Thevenin Resistance and the Thevenin Voltage
Vth =Rth I (Short Circuit)
The Attempt at a Solution
I know the answer is supposed to be Rth = 3Ω and Vth = 0.5V, but I couldn't get there with my method.
I only get the Rth to be 3 Ω if I first find the parallel equivalent of the two 3 Ω resistors and then have that be in series with the 1.5Ω resistor. If I try it the other way around though ( have the 1.5Ω resistor be in parallel with the 3Ω resistor, I get a different answer of 4 Ω.
Also I don't really understand how the Thevenin voltage would be found in this case as observed by the source because won't the absence of the voltage source cause the Vth to be 0V?
Help on this matter would be very much appreciated.
