A  220$\Omega$ 1/2 W  resistor has burned open, so you look in your parts box to find a replacement. Which one of the following resistors could you use to repair the circuit?

Quizplus · Accepted Answer

The replacement resistor must have the same resistance value as the original (220$\Omega$) and at least the same power rating (1/2 W or higher). Option C is the only one that meets both requirements. Option A has the correct resistance value but a higher power rating, option B has the correct resistance value but a lower power rating, and option D has both a lower resistance value and a lower power rating.
