A semiconductor device is connected in series in circuit with a battery and resistance. A current is allowed to pass through the circuit. If the polarity of the battery is reversed, the current drops to almost zero. The device may be:
A. a p-n junction diode
B. an intrinsic semiconductor
C. a n-type semiconductor
D. an p-type semiconductor
