The potential difference across a specialized platinum sensor filament is 7.56 V.
The current flowing through the filament is 0.18 A.
Calculate the resistance of this filament.
Use the equation:
potential difference=current×resistance \text{potential difference} = \text{current} \times \text{resistance} potential difference=current×resistance59 exam-style questions on Edexcel GCSE Physics 10.2 Resistance. Each one has a worked solution and a mark scheme showing where the marks go.
