The resistivity of an extrinsic semiconductor is about
Right Answer is:
2 Ω cm
At room temperature, the resistivity of an extrinsic semiconductor is typically a few ohm-cm while the resistivity of an intrinsic semiconductor is much higher and may depend on the density of unavoidable impurities in the material.
Since adding impurity to semiconductor material increases its conductivity, therefore, the resistivity is very small of about 2Ω cm to 5Ω cm
