A semiconductor has an electron concentration of `8xx10^(13)` per `cm^(3)` and a hole concentration of `5xx10^(12)` per `cm^(3)`. The electron mobilityis `25,000 cm^(2)V^(-1)sec^(-1)` and the hole mobility is `100cm^(2)V^(-1)sec^(-1)` and the hole mobility is `100cm^(2)V^(-1)sec^(-1)`  (i) The semiconductor is `n`-ty (ii) the semiconductor is `p`-type  iii) the conductivity is `320m mho cm^(-1)` (iv) the conductivity is `80m mho cm^(-1)`
