Testing pupils on parallel circuits

Diagnostic Questions for 11-14 Supporting Physics Teaching

What the Activity is for

The diagnostic questions can be used to check the pupils' understanding of parallel circuits.

What to Prepare

  • printed copies of the diagnostic questions (see below)

What Happens During this Activity

The questions might be used for homework or as the basis for discussion in class.

Identical resistors: designed to probe pupils' understanding of how voltage is dropped across identical resistors in a simple parallel circuit.

  • V1 is 8 volt
  • V2 is 8 volt

Power supply: designed to probe pupils' understanding of how voltage is dropped across identical resistors in a simple parallel circuit.

  • Voltage across bulb B1 is 4 volt
  • Voltage across bulb B1 is 4 volt; B2 is 4 volt
