Quizplus · Accepted Answer

In a parallel combination, the voltage across each resistor is the same. Therefore, the voltage across the 330$\Omega$ and 470$\Omega$ resistors will be the same. In the series combination, the resistor with the highest value will drop the most voltage. Therefore, the 1 $\mathrm { k } \Omega$ resistors will drop the most voltage.
