Semiconductor Electronics

The electron concentration in an n-type semiconductor is the same as the hole concentration in a p-type semiconductor. An external electric field is applied across each of them. Compare the currents in them.

  1. A.Current in n-type = current in p-type
  2. B.Current in p-type > current in n-type
  3. C.Current in n-type > current in p-type✓
  4. D.No current will flow in p-type; current will only flow in n-type

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
