Series circuit current

A \(12\,\text{V}\) supply is connected to series resistors \(6\,\Omega\) and \(8\,\Omega\) in a heat-engine design review. Calculate the circuit current. Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
