D2. Investigating and Understanding Concepts
Specific Expectations
D2.1
conduct investigations to explain the behaviour of electric charges in static and current electricity, and to relate the observed behaviour to the properties of subatomic particles and atomic structure
D2.2
determine the conductivity of various materials by investigating their ability to hold or transfer electric charges
D2.3
identify the components of a direct current (DC) circuit and explain their functions, and identify electrical quantities, their symbols, and their corresponding International System of Units (SI) units
D2.4
investigate the relationships between electric current, potential difference, and resistance in electrical circuits, and develop a mathematical model to represent the relationships
D2.5
apply a mathematical model to calculate electric current, potential difference, and resistance in real-world situations
D2.6
construct series and parallel circuits to compare electric current, potential difference, and resistance in both types of circuits
D2.7
explain the difference between electricity and electrical energy
D2.8
determine the efficiency of various electrical devices that consume or produce electrical energy, and identify the energy transformations in each device
