If the two ends of a p-n junction are joined by a wire: |
there will be a steady current from the n-side to the p-side There will be a steady current from the p-side to the n-side there will not be a steady current in the circuit There must be a steady current |
there will not be a steady current in the circuit |
The correct answer is Option (3) → there will not be a steady current in the circuit When two sides are connected, the electrons from the n-side will move to p-side, where they will combine with holes. This process create a depletion region at the junction, where no free charge carries is available. Thus, without any external voltage, there will be no steady current in the circuit. |
