A diode acts as a one-way valve for electricity. It allows current to flow freely in one direction (forward bias) but blocks it completely in the opposite direction (reverse bias). A triangle pointing toward a vertical bar.

Show a power supply block diagram and ask, "Where does the big capacitor go?" (Answer: After the rectifier to smooth DC ripple).

Active components are used to amplify, switch, or regulate electrical signals.

If you tell me the (e.g., middle schoolers, hobbyists, or engineering students), I can: Adjust the technical depth of the descriptions.

: Thousands of resistors, transistors, and capacitors shrunk down into one "chip."

A zigzag line (ANSI standard) or a rectangular box (IEC standard).

From Symbols to Reality Content: Engineers don't draw realistic pictures; they use standardized symbols. Quick Reference:
