The movement of free electrons in a conductor is called
7.
For a forward-biased diode, the barrier potential ________ as temperature increases.
8.
The wide end arrow on a schematic indicates the ________ of a diode.
9.
An n-type semiconductor material
Answer: Option
Explanation:
N-type Semiconductor :
An intrinsic semiconductor material is a poor conductor. When a small amount of pentavalent impurity is added to the intrinsic material its conductivity rises sharply. This material formed after the addition of pentavalent impurity to the intrinsic semiconductor material is called N-type material. Addition of small amount of pentavalent atoms in the intrinsic material provides large number of free electrons for conduction.
10.
For a forward-biased diode, as temperature is ________, the forward current ________ for a given value of forward voltage.
