A student uses a water bath to investigate how the electrical resistance of a thermistor changes over a temperature range from 15∘C15^{\circ}\text{C}15∘C to 90∘C90^{\circ}\text{C}90∘C.
State one modification the student could make to the experimental setup to investigate temperatures above 100∘C100^{\circ}\text{C}100∘C.
59 exam-style questions on Edexcel GCSE Physics 10.2 Resistance, covering 10.2.1 Current in a circuit and conservation at junctions, 10.2.2 Resistance and variable resistors, 10.2.3 Series and parallel resistance, 10.2.4 I–V characteristics of components, and 10.2.5 LDRs and thermistors. Each one has a worked solution and a mark scheme showing where the marks go.
