What is statement is true concerning the total resistance of a parallel circuit?
Official USCG Answer & Rule Citation
Correct Answer: Option B — The total resistance is smaller than the lowest branch resistance.
In parallel circuits, adding current paths decreases total opposition. Mathematically, the reciprocal of total resistance equals the sum of individual branch reciprocals, rendering the combined value perpetually less than the smallest individual resistor per IEEE 45 and basic DC circuit theory.
