About this document
Investigating Wire Resistance in Circuits by Pramudith Liyanage is a document available to read on EtoBox.
The IGCSE class is investigating circuits and resistance. Students measure the current and potential difference across wires of different diameters and lengths. They calculate resistance and observe that resistance is inversely proportional to cross-sectional area. Students then construct and analyze circuits with resistors in series and parallel combinations, measuring current and potential difference to calculate total resistance. They find that resistance is lowest in parallel circuits.
