What is the total resistance of four 100 Ω resistors in series?

Explanation:
When resistors are in series, the same current flows through each and the total resistance is the sum of their individual resistances. Four resistors at 100 ohms each add up to 400 ohms. So the total resistance is 400 Ω. If these were in parallel, the total would be less than 100 Ω, which is why the other numbers don’t apply here.
