A 600 pF capacitor is charged by a 150 V battery. The charge on the capacitor is:
- A 9 \( \mu\text{C} \)
- B 4 pC
- C 90 nC
- D 9 nC
Answer & Solution
Correct Answer
(C) 90 nC
Step-by-step Solution
Detailed explanation
\(Q = CV\) \(Q = (600 \times 10^{-12} \text{ F}) \times (150 \text{ V})\) \(Q = 90 \times 10^{-9} \text{ C} = 90 \text{ nC}\)
