Topic 5 General Notes

Practicals and simulations are an important part of this unit. Great opportunities to do calculations and make predictions to be test in real scenarios. I also get my students working with breadboards here so that they are familiar if the students take electronics in university.

Practical Ideas:
- Rubbing balloons on shirt/heads to create static charge

- Using ebonite and plastic rods with a wool cloth to create charge and demonstrate attraction/repulsion (potentially with the baloons)
​

- Using Van De Graff Generator to demonstrate static charge

Circuits Playlist (See  videos 1 and 3-8)
Practical Ideas:
- Having students identify resistors by their colour bands

- Testing different lengths of 0.1mm or 0.2mm nichrome wire to find the relationship between length and resistance (can calculate resistivity of the wire)

- Setting up resistors in parallel and series and determining equivalent resistance

- Providing a source with too high a voltage and having students make a potential divider circuit to light a light bulb without burning it out
​
- Using theoretical values and Kirchoff's laws to find expected currents/voltages and then using a simulation to demonstrate accuracy
