What is the total resistance in a series circuit with resistances of 3 ohms, 2 ohms, and 5 ohms?

In a series circuit, the total resistance is simply the sum of all individual resistances. This principle is fundamental to understanding how series circuits operate. The resistances in this scenario are 3 ohms, 2 ohms, and 5 ohms.

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

3 ohms + 2 ohms + 5 ohms = 10 ohms.

This calculation confirms that the total resistance of the series circuit is 10 ohms. Therefore, the correct answer reflects a basic yet essential concept in electrical engineering, emphasizing how resistances combine in series. Understanding this concept is crucial for analyzing and designing circuits effectively.
