Electricity and Magnetism

Many of the basic ideas can be studied with a range of capacitors (at least one with a large value, 10 000 mF or more) and...

Teaching Guidance 16-19

The equipment used in this topic is relatively basic. Look out for display meters, excellent for demonstrations, and which are...

Teaching Guidance 16-19

Most multimeters can function as ohm meters, for measuring resistance directly. They apply a small voltage to the component...

Teaching Guidance 16-19

It is essential to become well-versed in the use of an oscilloscope for displaying voltages. If you have access to more than...

Teaching Guidance 16-19

A joulemeter will be useful when discussing energy and power in electric circuits. It is worth practising with it before using...

Teaching Guidance 16-19

There are some tricky experiments in this topic, and it is well worth practising them in advance.

Teaching Guidance 16-19

Magnetic fields will have to be shown; iron filings are a standard way to do this, but you may also find a magnaprobe useful –...

Teaching Guidance 16-19

Students will have a simple idea of electromagnetic radiation.

Teaching Guidance 16-19

It is helpful to start this topic by discussing capacitors, rather than the more abstract notion of capacitance .

Lesson 16-19

Having established that there is charge on each capacitor plate, the next stage is to establish the relationship between...

Lesson 16-19

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...
