Capacitance unit conversion: Convert a capacitance of 0.00022 F into microfarads (µF).

Introduction / Context:Converting between farads and sub-multiples (µF, nF, pF) is routine in circuit design. This question assesses precision with scientific notation and unit scaling.

Given Data / Assumptions:

• C = 0.00022 F.
• Find the equivalent in microfarads.

Concept / Approach:1 µF = 10^-6 F, hence to convert farads to microfarads, divide by 10^-6 (or multiply by 10^6).

Step-by-Step Solution:C(µF) = C(F) * 10^6C(µF) = 0.00022 * 10^6C(µF) = 220 µF

Verification / Alternative check:Back-convert: 220 µF = 220 * 10^-6 F = 0.00022 F, matching the original value.

Why Other Options Are Wrong:

• 22 µF: 10x too small.
• 2,200 µF: 10x too large.
• 22,200 µF: 100x too large.

Common Pitfalls:Misreading decimal places or confusing milli (10^-3) with micro (10^-6) leads to power-of-ten mistakes. Always track exponents explicitly.

Final Answer:220 µF
