What is the purpose of the depletion region in a semiconductor diode?

  1. To create a channel for unrestricted current flow in both directions.
  2. To amplify current passing through the diode.
  3. To establish a potential barrier that regulates current flow based on biasing conditions. ✓
  4. To generate light when the diode is forward biased.

Explanation

Cash: immediate, anonymous, but risky for large amounts. Cheque: written order to bank to pay; requires clearing (2-3 days). Bank draft: guaranteed by bank; safer than personal cheque.

Electronic transfer: direct bank-to-bank movement of funds. Standing order: regular fixed payments (rent). Direct debit: variable amounts withdrawn by recipient (utility bills).

Cards: debit (from bank account), credit (borrowed, pay later with interest). Mobile money (very popular in Nigeria): use phone to store and transfer funds. Each method suits different situations.
