Question

derive an expression for electric energy consumed in a device in terms of V, I,T where is the potential difference applied to it I is the current draw by it T is the time for which current flow​

Answer 1

potential difference=work done/charge

v = w/q

w = v*q---------(1)

If 'I' flows through the conductor for time't' then total charge flowing through the conductor is given by

q = It

substitute the value'q' in eq. (1)

w = v*It

E =vIt(joule)

work done=electric energy=heat

w=E=H

I hope you understand this derivation.
