Animations are used to descibe the difference between series and parallel circuits. The presenters then show how ammeters can be used to measure current and voltage at different points in the circuit.

Students could try and record current using an ammeter in a simple series circuit (a cell and a bulb) and a simple parallel circuit (a cell and two bulbs). This could be repeated using a voltmeter. Does this change if they introduce a different component, for example a buzzer or a motor?
