Performances of Understanding for TfU Unit "D.C. Circuits" Sec. 4 Da Vinci Class, Teck Whye Secondary School, Singapore
Cugan and Faiz of Sec. 4 Da Vinci designed a series circuit.	Akid tried out whether the circuit design would lead him to the aim of the investigation.	Cugan and Faiz recorded the measurements that they had taken.
Sufree and Arun too were trying out their circuit design.	Sarah and Xiang Yun interpreted their experimental data.	Kenneth recorded the observations that he and Miguel made. Their observations were the climax of the PU as they led to the two important mathematical relationships for current and potential difference: I = and V =
The circuit, designed by Kenneth and Miguel, was the stimulus for the guided derivations of the equations for current and potential difference in series circuits.	Cugan and Faiz went on to find out more about the equations by increasing the e.m.f.	TfU in action!
