If potential difference between plates of parallel plate capacitor is doubled then energy stored in it will ______?
Everyday Science / Physics — Multiple-choice practice
اگر متوازی پلیٹ کیپسیٹر کی پلیٹوں کے مابین ممکنہ فرق دوگنا ہوجاتا ہے تو پھر اس میں موجود توانائی ______ ہوگی؟
- A. Four times
- B. Remains same
- C. None of these
- D. Two times
Correct answer
Four times
Explanation
Explanation The energy stored in a capacitor is given by U = (1/2)CV². If the potential difference (V) is doubled: U ∝ V² U' ∝ (2V)² = 4V² So, the energy stored will increase by a factor of 4 .
