  • DIron


Fill in the blanks: A compact fluorescent lamp consumes electric current than light bulbs and has a much working time.

  • Amore, lower
  • Bless, higher
  • Cless, lower
  • Dmore, higher


Look at this table.

Row 1It has 1 filament made of tungsten.It is filled with argon gas.Its connection points are at the base.
Row 2It has 2 filaments of tungsten.It is filled with argon gas and a small amount of mercury.It has 2 connection points, one at each tip.Its inner surface is covered with a phosphoric material.

Which row shows the features of a fluorescent lamp?

  • A2
  • B1


Fill in the blanks: Tungsten is used as a filament in electric lamps because it has a . This prevents it from due to the heat of the lamp.

  • Ahigh melting point, melting
  • Blow melting point, melting
  • Chigh boiling point, boiling
  • Dlow boiling point, boiling


Look at this fluorescent lamp.

What is the function of the glass tube?

  • AIt stops the filament melting.
  • BIt connects the fluorescent lamp to the electricity source.
  • CIt holds the argon gas and mercury vapor.
