Question 12: OpenResponse 

Reporting Category: Electromagnetism Standard: 5.3  Analyze simple arrangements of electrical components in both series and parallel circuits. Recognize symbols and understand the functions of common circuit elements (battery, connecting wire, switch, fuse, resistance) in a schematic diagram.

The diagram below shows a circuit with four numbered electrical components.
 Identify each of the numbered components of the electric circuit and describe its function.
 The current in the circuit is 0.5 A. Describe two changes to the circuit that would decrease the current in the circuit.

Scoring Guide and Sample Student Work Select a score point in the table below to view the sample student response.
Score  Description 
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.
