When a semiconducting device is connected in series with a battery and a resistance, a current is found to flow in the circuit. If however, the polarity of the battery is reversed, practically no current flows in the circuit. The device may be
Options:
Answer:
D
Solution:
When the battery and resistance is connected with diode,
In case of forward bias that is connected to + ve terminal of battery, current flows. If one reverse the polarity i.e., -end is made negative, no current flows in semiconductor diode.
