What to Focus On

  • Current from a cell or battery is direct current.
  • Current from mains or a generator is alternating current.
  • Household supply is A.C. at 220 V.
  • A house supply cable has live, neutral, and earth wires.
  • Live wire: 220 V, red or brown, carries current from source to appliance.
  • Neutral wire: 0 V, black or light blue, provides return path.
  • kWh is the commercial unit of electrical energy.
  • 1 kWh = 3.6 × 10^6 J.
  • Energy in kWh = Power in kW × time in h.

Common Mistakes to Avoid

The neutral wire carries current from the source to the appliance, and the live wire only brings it back.

The fuse should be connected to the neutral wire because it is the return path.

A fuse wire should be thick and made of copper so that it can carry more current safely.
