Difficulty: Easy
Correct Answer: 60 µF
Explanation:
Introduction:
Capacitance relates stored charge to voltage. For a lumped capacitor, the basic definition C = Q / V directly gives the required value when charge and voltage are known. Unit handling is crucial to avoid order-of-magnitude mistakes.
Given Data / Assumptions:
Concept / Approach:
Use the definition C = Q / V. Convert microcoulombs to coulombs: 1 µC = 1e-6 C. After calculation, express the result in a convenient unit (µF).
Step-by-Step Solution:
Verification / Alternative check:
Back-calculate charge with C = 60 µF at 25 V: Q = C * V = 60e-6 * 25 = 0.0015 C = 1500 µC, confirming correctness.
