ScoreDescription
4 The response demonstrates a thorough understanding of the components of a circuit, their function, and the corresponding symbols used in schematic diagrams. The response correctly identifies each component and clearly describes its function. The response also clearly describes two changes to the circuit that would decrease the current.
4
3 The response demonstrates a general understanding of the components of a circuit, their function, and the corresponding symbols used in schematic diagrams.
2 The response demonstrates a limited understanding of the components of a circuit, their function, and the corresponding symbols used in schematic diagrams.
1 The response demonstrates a minimal understanding of the components of a circuit, their function, and the corresponding symbols used in schematic diagrams.
0 The response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.
