What is the total resistance of three resistors (1k, 2k, 4k) in series?

Explanation:
In a series circuit, the total resistance is the sum of all individual resistances. Add them: 1k + 2k + 4k = 7k ohms. So the total resistance is 7k ohms, which is the value shown for the correct choice. The other numbers come from leaving out a resistor or mis-summing, which isn’t how series resistance works.
