Ah, my bad, please disregard the first circuit. The current source on the right should be 2A not 0.5A.Looking at the circuit, I would say Va is 10V, and Vb is 2.5V, so the difference is 7.5V...
Thanks. Totally overlooked that. I understand now.How can I2 = -2A if we clearly have an open circuit in loop2?
How is Va equal to 0 V? You have a 2 A current source and, because of the open circuit, all 2 A must flow down through the 5 Ω resistor. Sure seems like that would make Va equal to 10 V.Then Vb is 10V and Va is 0V, if it's an open circuit.
