Power dissipated in a resistor
In a second version of the same investigation, A resistor in a electric scooter battery check carries current \(1.2\,\text{A}\) and has resistance \(21\,\Omega\). Calculate the power dissipated. Use the diagram first, then calculate the requested value. 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.
