In a schematic, what voltage would be found across l1 to l2?

In a typical electrical system, the voltage found across two lines l1 and l2 depends on the configuration of the electrical supply and the specific system design. When considering common residential or commercial setups, l1 and l2 often represent two different phases in a split-phase system. In this case, these two lines would typically be at 240 volts relative to each other.

However, if the context of the question pertains to a different electrical system configuration, such as a single-phase system where the measurement is taken across a single phase and neutral, 120 volts would be appropriate. This scenario is common in North American residential wiring, where one phase (l1) relative to the neutral would present a voltage of 120 volts.

The other potential voltages mentioned, such as 240 volts, 480 volts, and 60 volts, correspond to different configurations and systems. For example, 240 volts would represent the total voltage across two phases in a three-phase system, while 480 volts is often indicative of high-voltage industrial applications. A voltage of 60 volts does not typically apply to standard residential or commercial wiring scenarios.

In this question, if the context indicates a standard setup typically found in residential wiring, the voltage found across l
