Find V1. I attached a picture for the circuit.
The Attempt at a Solution
This is what I did (Refer to Fig. 1):
-2A + (V1)/(50) +(V1-45)/(1) = 0
But when I looked at the solution my professor posted this is what he did (Redrew Fig.1 as Fig.2):
-2A + (V1)/(50) +(V1-45)/(1+4) = 0
I thought you were finding the potential difference between V1 and the voltage source? I don't understand why he included the 4Ω resistor. Any help is appreciated!
