Question

Prove that qv=Delta E.

Answer 1

Q is the charge on the object
V is the potential difference

Sometimes this equation is written as E = QV where E is the energy.

Answer 2

Nope, it was thermodynamics
And it was one it's process.
Process at constant volume OR qv= delta E!

I've figured it out already!

But, thankyou for replying!
