The correct answer is

500 V

To solve this problem, we need to determine the voltage across each load in a balanced delta-connected system. We have the following information:
Impedance (Z) = 100 Ω
Current per phase (Iphase) = 5 A

In a delta-connected system, the voltage across each load (Vphase) can be found using Ohm's Law:

Vphase = Iphase × Z

Substitute the given values into the equation:

Vphase = 5\ A × 100\ \Omega = 500\ V

Therefore, the voltage across each load is 500 V.

Thus, the correct answer is 500 V.
