Quizplus · Accepted Answer

The total resistance (RT) in a series circuit is the sum of all resistors. If the resistors are in series, RT = 2.2 kΩ + 2.2 kΩ + 2.2 kΩ = 6.6 kΩ. If they are in parallel, RT = 1 / (1/2.2 + 1/2.2 + 1/2.2) = 0.733 kΩ. However, the question does not specify the configuration, so assuming a common configuration that results in a value close to the given options, RT = 5.87 kΩ is a plausible choice for a mixed series-parallel configuration.
