Demonstration: shows that electrostatic charges are the same as the charges passing through wires and components in electric...
Demonstration: to some students the feeling for coulombs of charge comes most easily from electrolysis.
Demonstration: the electrolysis of water yields oxygen and hydrogen gases and simple calculations estimate the charge of the...
Demonstration: experiments to show that current (and therefore charge) is conserved around a circuit. They can be teacher...
Class practical: a minute current in the base-emitter circuit is used to control a much larger current in the collector...
Demonstration: an approach to Ohm's law in a quick demonstration.
Class practical: this experiment looks at the relationship between current and potential difference (p.d.) for a length of...
Demonstration: solutions may show ohmic or non-ohmic characteristics.
Demonstration: gases conduct electricity, but they have to be ionised first.
Class experiment: the fact that current is the same all round a series circuit may have been discovered when using ammeters...
Challenge your students to think about making conducting circuits in seasonal/non-seasonal shapes, using circuit components.
In this activity students observe a rope loop being circulated. You can use it as a model to introduce circuits.
