A 10 μF capacitor is charged to 10 V. How much charge does it store?

Answer and explanation

Correct answer: B. 100 μC

  1. Step 1: Q = CV. Step 2. Q = 10 × 10 = 100 μC. Answer: 100 μC. Why not the others: 1 μC is what you get if you divide C by V. 500 μC is what you get if you give the energy formula value. 20 μC is what you get if you add the numbers.
