If potential difference between plates of parallel plate capacitor is doubled then energy stored in it will ______?
اگر متوازی پلیٹ کیپسیٹر کی پلیٹوں کے مابین ممکنہ فرق دوگنا ہوجاتا ہے تو پھر اس میں موجود توانائی ______ ہوگی؟
Answer: Four times
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.
