In case a pn-junction is forward biased:

WebExplain how the p-n junction is formed otherwise it is an ion and has a net positive or negative charge. 3. Explain the operation of forward-biased and The number of protons reversed bias of p-n junctions determines the type of atoms 4. Extract the information from i-v characteristic of p-n junction WebUnder the forward bias, the electrons in the p-type region move collectively towards the positive terminal. This includes the electrons in the p-surface but it is supplanted immediately after it left by electrons from the n-region. Therefore, p-region gained equal electrons as it has lost so no charge difference.
