A student says: in the depletion layer of an unbiased p-n junction there are no charges at all, so there is no electric field in it. Which reply is correct?
The layer has no free carriers but it has fixed ions, which make a field
The student is right, since there are no free carriers
The layer has free carriers of both signs, so the field is zero
The field is there only when a battery is connected

← A small lamp of fixed resistance 260 Ω is in a loop with a cell of 6.4 V and a germanium diode. The diode is connected so that it conducts, and it drops 0.3 V. How much current does the lamp carry?
A forward-biased silicon diode carries 4.0 mA. Take VT = 26 mV, and the ideality factor 1. What is the dynamic resistance of the diode at this current? →
