Question: 1 / 495

If three resistors of 10.0 ohms each are connected in series, what is the total resistance?

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, each of the three resistors has a resistance of 10.0 ohms. To find the total resistance, you would take the resistance of the first resistor, add it to the second resistor, and then add that sum to the third resistor.

The calculation would be as follows:

Total Resistance = 10.0 ohms + 10.0 ohms + 10.0 ohms = 30.0 ohms.

This means that when you have multiple resistors in series, their resistances add up linearly, resulting in a higher total resistance. Understanding this principle is crucial when examining circuits since it allows for accurate predictions of how changes in resistor configurations affect overall resistance.
