The derivation of formulae for capacitors in series and parallel will help to reinforce your students’ understanding of...

Lesson 16-19

So far, we have not considered the question of energy stored by a charged capacitor. Take care; students need to distinguish...

Lesson 16-19

Students will have already seen that the discharge is not a steady process in episode 125, but it is useful to have graphical...

Lesson 16-19

There are many examples of exponential changes, both in physics and elsewhere. Your specification may require that you make a...

Lesson 16-19

Depending on the ability and experience of your students you may need to spend time reviewing their previous knowledge and...

Lesson 16-19

Here, you are trying to illustrate the idea of electric charge and its relationship to a flow of current.

Lesson 16-19

There are two main aims for this episode: to present a range of examples involving different types of charge carrier, and to...

Lesson 16-19

In this episode, you can show that charge carriers in good conductors usually move very slowly.

Lesson 16-19

It is worth discussing energy transfer in electric circuits and linking this by analogy to other more familiar examples.

Lesson 16-19

Students may need to be reminded of the idea that power is the rate of doing work (or the rate at which energy is transferred)...

Lesson 16-19

The idea of resistance should be familiar (although perhaps not secure) from pre-16 science course, so there is no point...

Lesson 16-19

In this episode, students measure the current and voltage characteristics for several components, and identify ohmic and non...
