The driving force for diffusion currents in a semiconductor is: Group of answer choices An external voltage connected to a semiconductor. Inhomogeneous charge carrier densities. None of the other answers are correct. Homogeneous charge carrier densities.

it becomes positively charged by charging it

i think the answer is tomato juice? not entirely sure though

k2s for potassium sulphide

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
