PS3A - Definitions of Energy
In this video Paul Andersen attempts to explain the age old questions - What is Energy? Even though it comes in many forms one of the defining characteristics of energy is that it is conserved over time. He then explains that all...

Changing voltage
Pupil outcome: I can describe and apply the rules for voltage in a series circuit. Key learning points: - The voltage of a battery measures the strength with which it can ‘push’ current around a circuit. - The voltage of a component in...
