What to Focus On

  • An electric cell is a portable source of electrical energy.
  • An electric cell has two terminals: positive and negative.
  • The positive terminal is the metal cap and the negative terminal is the metal disc.
  • The thin glowing wire in an incandescent lamp is called the filament.
  • The filament is attached to two thicker wires that act as terminals.
  • An LED has no filament.
  • A complete circuit is needed for current to flow.
  • Current is taken to flow from the positive terminal to the negative terminal of a cell.
  • A switch completes or breaks a circuit.

Common Mistakes to Avoid

A battery always means two or more cells connected together.

An incandescent lamp glows only if its terminals are connected in one fixed order.

An LED glows in any direction if the circuit is complete.

Memory Tips

Electric cell is a portable source of electrical energy

Positive and negative terminals of an electric cell

Battery is two or more cells connected in series

Battery gives more time and/or more energy
