A
576.9 nanofarads
B
1,733 picofarads
C
3,583 picofarads
D
10.750 nanofarads
Answer Notes
When capacitors are connected in parallel, their total equivalent capacitance is calculated by simply adding their individual values together (C_total = C1 + C2 + C3).
Before you can add these values, they must all be in the same unit. The question gives two values in nanofarads (nF) and one in picofarads (pF). Convert 750 pF to nanofarads by dividing by 1000, resulting in 0.75 nF.
Finally, add the standardized values together: 5.0 nF + 5.0 nF + 0.75 nF equals 10.75 nF. Distractors often result from ignoring the unit prefix difference or using the reciprocal series formula by mistake.
