Class practical: adding a shunt in parallel with a galvanometer converts it to an ammeter with a higher range. This is a trial...
Class experiment: circuit diagrams allow students to make simple records. They also allow teachers to give students summaries...
Class experiment: many interesting circuits can be set up with switches in series and in parallel with components.
Class experiment: the fact that current is the same all round a series circuit may have been discovered when using ammeters...
Class practical: an extra wire can shed light on the problem.
Demonstration: an introduction to what voltmeters measure and how they are connected in circuits.
It is often up to a teacher and a particular class to decide what equipment to use to introduce electric circuits.
At some point during the early teaching of electric circuits, students will want to know what an electric current is. Indeed...
Questions to review current thinking, to provoke thought and discussion.
These diagnostic questions are used for two main reasons: to encourage students to talk and think through their understandings...
