A simple circuit is examined to introduce the measurement of the
strength of an electric current. It is assumed that the students
understand the term current and its unit.
When they know that electric current is defined as the number of
freely moving electrons which pass a cross-section of a conductor
in a unit of time, they will easily understand that in this case
the measuring instrument must be connected in series.
Set up a simple circuit incorporating a filament lamp
and familiarise yourself with the way the strength of an
electric current is measured.
