Can we measure the potential differnece across an unbiased p-n junction by connecting a sensitive voltmeter across its terminals? Explain

answered-by-expert Expert Answer
No. Potential difference across p-n junction is not electro-motive force. Potential difference occurs only when it is forward biased.
 
Under biased condition there is a movement of charge carriers.
 
Due to this movment of charge carrieres we observe there is a potential difference occurs across p-n junction

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
