That's the thing that bothers me a lot. What is the physical reality that corresponds to no solution? does that mean no current anywhere or what?Correct. The solution is: There is no solution.
To confirm this"
Taking the "outer" loop, in a clockwise direction (The loop containing only the 10V and 5V sources.) gives you:
10V − 5V = 0.
That's a contradiction.
No. It's a physically impossible situation if those are "ideal" sources of voltage. ##I_1 \to \infty## and ##I_3 \to -\infty## .That's the thing that bothers me a lot. What is the physical reality that corresponds to no solution? does that mean no current anywhere or what?
Thank you!No. It's a physically impossible situation if those are "ideal" sources of voltage. ##I_1 \to \infty## and ##I_3 \to -\infty## .
It's much like a short circuit.
This clears my mind, thank youThis is one of the invalid connections in circuit theory. You can't connect two unequal ideal voltage sources in parallel and two unequal ideal current sources in series.
