Unit comparisons: a capacitor of 0.02 µF is larger than which of the following equivalent-value expressions?

Introduction / Context:Comfort switching between F, µF, nF, and pF prevents costly sizing mistakes. Here we compare magnitudes by converting all options to the same unit scale.

Given Data / Assumptions:

• Reference value: 0.02 µF.
• Assume ideal capacitors; we only compare numeric magnitudes.

Concept / Approach:Use 1 µF = 1000 nF = 10^6 pF. Then compare each candidate to 0.02 µF (which equals 20 nF = 20,000 pF). The reference is larger than values less than 20,000 pF and smaller than values greater than 20,000 pF.

Step-by-Step Solution:

Verification / Alternative check:Cross-check by µF directly: 2,000 pF = 0.002 µF; 0.02 µF > 0.002 µF is true.

Why Other Options Are Wrong:

• 200,000 pF and 0.000020 F: Both correspond to larger capacitances than 0.02 µF.
• All of the above: False because not all listed are smaller than 0.02 µF.
• 20 nF: Exactly equal to 0.02 µF, not smaller; the prompt asks “larger than.”

Common Pitfalls:

• Misplacing decimal points when converting pF to µF.
• Confusing “larger than” with “equal to.”

Final Answer:2,000 pF
