The Ⓥ symbol represents a voltmeter rather than a power source so virtually no current will flow in the first circuit.

In the second circuit, the right pair of hitmen is shorted so the voltage across them is zero while the current through the rightmost path can be very high. It can be simplified into two circuits: a. one with 2 shorted hitmen, b. one with one series pair of hitmen in parallel to a “resistor” and voltmeter.
Assuming the two hitmen are committing to a battery, the “b” circuit actually makes sense.
