Question

Prove that energy stored in a parallel plate cappacitor can be expressed by the relation Q^2/2C

Answer 1

Answer:

Let charge on plates are -q and +q , distance between parallel plates is d , electromotive force of battery which is connected to capacitor is V. As we know, q = CV , where C is capacitance of capacitor. We know, workdone stored in system is named as potential energy I'd system

Answer 2

$\huge{\green{\boxed{\boxed{\underline{\red{αηsωєя}}}}}}$

Let charge on plates are -q and +q , distance between parallel plates is d , electromotive force of battery which is connected to capacitor is V.

As we know,

$\large\boxed{q = CV}$

where C is capacitance of capacitor.

We know, workdone stored in system is named as potential energy I'd system.
