Three resistors of 5 Ω, 5 Ω, and 10 Ω are connected in series. What is the total resistance?

Explanation:
In a series arrangement, the same current passes through every component, so the total resistance is the sum of each resistor’s value. Add them: 5 Ω + 5 Ω + 10 Ω = 20 Ω. So the total resistance is 20 ohms. The other numbers would come from missing one resistor or misapplying the idea that you only add some of the resistances, not all of them in series.
