Parallel circuits
These diagnostic questions and response activities (contained in the zip file) support students in being able to:
- Identify a range of circuit diagrams that represent the same parallel circuit.
- Describe how to measure the voltage across the battery and across each branch of a parallel circuit.
- Describe the rule for voltages in a parallel circuit.
- Explain how a parallel circuit is like a set of nested simple-series circuits.
- Predict the voltage of batteries connected together in parallel.
- Describe how to measure current through the battery in a parallel circuit.
- Describe how to measure current through each branch in a parallel circuit.
- Describe the rule for current in a parallel circuit.
- Explain how the size of electric current in each branch depends on the voltage across the branch and the resistance of components in the branch.
- Explain changes in a parallel circuit when an extra branch is added.
The resources include details of common misconceptions and a summary of the research upon which the resources are based.
Download the zip file for all the questions and activities.
