Question: 1 / 495

What is the total resistance when three resistors of 10.0 ohms each are connected in series?

10.0 ohms

20.0 ohms

30.0 ohms

When resistors are connected in series, the total resistance is simply the sum of the individual resistances. In this case, you have three resistors, each with a resistance of 10.0 ohms.

To find the total resistance, you add the resistance values together:

10.0 ohms + 10.0 ohms + 10.0 ohms = 30.0 ohms.

Thus, the total resistance for the three resistors connected in series is 30.0 ohms, making it the correct choice. Understanding this concept is crucial for calculating total resistance in series circuits, as it allows for straightforward calculations based on the given values of individual resistors.
