Electricity and Magnetism

Demonstration: shows that electrostatic charges are the same as the charges passing through wires and components in electric...

Practical Activity 14-16

Demonstration: to some students the feeling for coulombs of charge comes most easily from electrolysis.

Practical Activity 14-16

Demonstration: the electrolysis of water yields oxygen and hydrogen gases and simple calculations estimate the charge of the...

Practical Activity 14-16

Demonstration: experiments to show that current (and therefore charge) is conserved around a circuit. They can be teacher...

Practical Activity 14-16

Class practical: a minute current in the base-emitter circuit is used to control a much larger current in the collector...

Practical Activity 14-16

Demonstration: an approach to Ohm's law in a quick demonstration.

Practical Activity 14-16

Class practical: this experiment looks at the relationship between current and potential difference (p.d.) for a length of...

Practical Activity 14-16

Demonstration: solutions may show ohmic or non-ohmic characteristics.

Practical Activity 14-16

Demonstration: gases conduct electricity, but they have to be ionised first.

Practical Activity 14-16

Class experiment: the fact that current is the same all round a series circuit may have been discovered when using ammeters...

Practical Activity 14-16

Electrical phenomena result from a fundamental property of matter - electric charge. The atoms that constitute most matter we...

Teaching Guidance 14-16

Once your students understand how circuits can be set up, it is time to introduce them to the idea of the lamp as an informal...
