A 2 μF capacitor is charged to 12 V. How much charge does it store?
Answer and explanation
Correct answer: D. 24 μC
- Step 1: Q = CV. Step 2. Q = 2 × 12 = 24 μC. Answer: 24 μC. Why not the others: 0.167 μC is what you get if you divide C by V. 144 μC is what you get if you give the energy formula value. 14 μC is what you get if you add the numbers.
