The voltage across the energized contacts in line #8 during operation is:

Explanation:
When a contact is energized, it means the switch or relay is closed, creating a conducting path between its terminals. The voltage drop across a closed, low-resistance path is extremely small because V = I × R. Even with substantial current, the contact’s resistance is so small (milliohms range) that the resulting voltage drop is only a few millivolts, effectively 0 V in practice. So the voltage across the energized contacts during operation is essentially zero volts. If the contact were open, you’d see the full line voltage across it, but a closed contact presents negligible drop.
