Electricity
In order to design electrical items like iPhones or drones we need to
understand how electricity works. This topic will give you a greater
understanding of electricity.
To be able to draw and interpret
circuit diagrams.
To know what is meant by current,
charge and potential difference.
To be able to calculate charge flow.
Thermistor – an electrical resistor whose resistance is
greatly reduced by heating.
Fixed resistor – limits current flowing in a circuit
Variable resistor – varies current flowing in a circuit
Light Dependent Resistor (LDR) -
To be able to draw and interpret

Other Components and their symbols:
Diode – allows current in ONE DIRECTION ONLY.
Light Emitting Diode (LED) – Emits light and only allows
current in ONE DIRECTION.
Fuse – a wire that melt when current is TOO high.
