Demonstration: in this simple demonstration with a fine beam tube you can show an electron beam. You can also bend it using an...

Practical Activity 14-16

Class practical: this experiment, for advanced level students, shows that the current through a thermistor increases with...

Practical Activity 14-16

Demonstration: a candle flame is electrically conductive. An EHT will visibly separate its free charges, causing a current to...

Practical Activity 14-16

Demonstration: a qualitative experiment to show the principle of a force on a charged body between two parallel plates.

Practical Activity 14-16

Demonstration: this introduces the construction of a capacitor and shows that a capacitor stores and releases charge.

Practical Activity 14-16

Class practical: to measure the current through and potential difference across a lamp as it is switched on.

Practical Activity 14-16

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...
