Parallel equivalent resistance

In a second version of the same investigation, Two resistors \(6\,\Omega\) and \(14\,\Omega\) are connected in parallel in a low-voltage lamp circuit. Calculate the equivalent resistance. 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.
