In a circuit with resistors connected to a voltage source, the voltage across the circuit depends on how the resistors are arranged (series or parallel) and their respective resistance values. However, if the total resistance in the circuit equals the voltage source (in this case, 12 V), the voltage can be divided among the resistors depending on their resistance.

If the answer indicated is 2 V, it might suggest that the resistors in this hypothetical scenario provide a specific division of the total voltage that is not standard or in accordance. For example, in a scenario where one resistor is significantly smaller than others in series, it may result in a situation where the voltage drop across that smaller resistor could be 2 V.

In general, however, to conclude that the voltage across a circuit with a total of 12 V source is specifically stated as 2 V without additional data on the resistance values or configuration is insufficient context. Therefore, without clear information on how these resistors divide the voltage, it could be argued that virtue alone does not sufficiently define the voltage across the full circuit.

Therefore, setting a total voltage of 12 V would generally mean that voltage is distributed across the circuit components according to Ohm's law and the
