Correct option is B
Explanation: In a three-phase electrical system, if the load impedance of the three phases is not equal, the load is considered
unbalanced. An unbalanced load results in unequal currents in the three phases, which can lead to inefficiencies and potential damage to equipment.
·
Unbalanced supply refers to a situation where the voltages in the three phases are not equal.
·
Balanced load refers to a situation where the load impedance in all three phases is equal, resulting in equal currents.
·
Balanced supply refers to a situation where the voltages in all three phases are equal.
In this case, since the load impedance is unequal, the correct term is
unbalanced load.
