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؟

Remains same

Two times

Four times

None of these

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.
