A heating element designed for a thermal imaging camera's de-misting window has a potential difference of 7.56 V7.56\text{ V}7.56 V across it.
The current flowing through the heating element is 0.24 A0.24\text{ A}0.24 A.
Calculate the resistance of this heating element. 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.
