# Testing pupils on series circuits(Activity)

### Diagnostic questions on series circuits

What the activity is for

The diagnostic questions can be used to check the pupils' understanding of key ideas introduced in this episode.

What the activity is for

• printed copies of these diagnostic questions

• Support sheet

What happens during this activity

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

Resistors in series: designed to probe pupils' understanding of how voltage is shared between two identical resistors in series.

(a) V1 reads 3 volt (b) The battery voltage is shared, half across each resistor.

Different batteries: probes pupils' understanding of the relationship between the battery voltage and the total voltage across external resistors. CharList

• V1 is 6 volt; V2 is 3 volt
• EndList

Different resistors: probes pupils' understanding of how voltage is shared between unequal resistors.

CharList

• V1 is 4 volt; V2 is 5 volt; V3 is 4 volt
• EndList

Bigger resistance: probes pupils' understanding of how voltage is shared between unequal resistors.

CharList

• V1 reads between 6 volt and 3 volt
• The battery voltage is shared, with the larger share across the larger resistor.
