Electric Wires

⚡ What Are Electric Wires?

Electric wires are conductors used to carry electrical current from a power source to devices, appliances, or equipment. They are essential in homes, industries, vehicles, and electronics.

🧱 Main Parts of an Electric Wire

1. Conductor

   • Usually copper (most common) or aluminum

   • Carries the electric current

2. Insulation

   • Made of PVC, rubber, XLPE, or Teflon

   • Prevents electric shock and short circuits

3. Sheathing (optional)

• Extra outer protection against heat, moisture, or mechanical damage

🔌 Types of Electric Wires

1. Single-Core Wire

• One solid conductor

• Used in house wiring (inside conduits)

2. Multi-Core Wire

• Multiple insulated conductors in one cable

• Used for appliances, extension cords

3. Flexible Wire

• Made of many thin copper strands

• Used for irons, chargers, electronics

4. Armored Cable

• Has metal protection

• Used underground or in industrial areas

5. Overhead Power Lines

• Bare or insulated

• Used for electricity distribution on poles

🎨 Wire Color Codes (Common Standards)

Single Phase (AC – Home Wiring)

• Brown / Red → Live (Phase)

• Blue / Black → Neutral

• Green-Yellow → Earth (Ground)

⚠️ Color codes may vary by country.

📏 Wire Sizes (Thickness)

Measured in:

• mm² (most countries)

• AWG (American Wire Gauge)

Examples:

• 1.5 mm² → Lighting

• 2.5 mm² → Sockets

• 4–6 mm² → Cooker, AC

Thicker wire = carries more current safely.
