Question

Draw the symbol of (i) PN junction diode (ii) Zener diode.

Answer 1

(i) PN Junction Diode

The symbol for a standard PN junction diode consists of a triangle pointing towards a bar. The triangle represents the Anode (A) and the bar represents the Cathode (K). The arrow indicates the direction of conventional current flow.

• Anode (A): The positive terminal.
• Cathode (K): The negative terminal.

(ii) Zener Diode

The symbol for a Zener diode is similar to a standard diode, but the cathode line is bent at both ends, often resembling the letter 'Z'. This unique cathode symbol distinguishes it from a regular diode.

• Anode (A): The positive terminal.
• Cathode (K): The negative terminal (represented by the Z-shaped bar).
