During operation, what voltage would be found across the contacts when energized in line #8 according to the schematic?

In electrical circuits, the voltage across contacts when energized is determined by the design and configuration of the circuit. In this case, if the schematic indicates that line #8 is supplying a voltage of 240 volts, then when the circuit is energized, the contacts in that line would also exhibit a voltage reading of 240 volts. This is indicative of how the system is wired and the standard voltages available for certain scenarios, particularly in industrial and commercial applications where 240 volts is a common voltage level for powering larger equipment.

Understanding this voltage measurement is integral to troubleshooting and operational practices in electrical systems, as it helps technicians gauge whether components are functioning properly or if there is an issue affecting the voltage supply.
