Valid connections

    I'm not really sure about this. If someone could just explain the concept so i can figure it out, it would be much appreciated. Neither one of them looks like a valid connection, but i have no experience with this.

    Test: put a resistor across the terminals and determine if you can compute a current and voltage (obviously voltage will = current x R).

    Put two differing current sources in series and try to do the same. Can you come up with a current?

    Try to do the same with two differing voltage sources in parallel. What then?

    I don't have any parts to test on. I was just learning about in series and parallel resistors, but mostly about finding equivalent resistors.

    I don't mean use actual components. Draw the schematic with the resistor shunting the network terminals and try to write KCL or KVL equations that aren't self-contradictory.
