Resistance from voltage and current
A component in a low-voltage lamp circuit has potential difference \(6\,\text{V}\) and current \(0.4\,\text{A}\). Calculate its resistance. Enter the numerical result and choose the interpretation that matches the physical meaning.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
