25. Derive an expression for electric energy consumed in a device in terms of V. 1 and t, where V is potential difference applied to it. I is the current drawn by it and t is the time for which the
current flows? State the law associated with heating effect?​

gravitational energy

electrical energy

kinetic energy

ligh energy

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
