Final answer:
To find the equivalent series resistance for resistors in series, add their values together. For 3.10 kΩ, 1.20 kΩ, and 0.60 kΩ resistors, the total is 4.90 kΩ.
Step-by-step explanation:
To calculate the equivalent series resistance Rs when three resistors are connected in series, you simply add their resistance values together. For the resistors with values 3.10 kΩ, 1.20 kΩ, and 0.60 kΩ, the total equivalent series resistance is calculated as:
Rs = R1 + R2 + R3
Replacing R1, R2, and R3 with the given values:
Rs = 3.10 kΩ + 1.20 kΩ + 0.60 kΩ
Rs = 4.90 kΩ
Therefore, the equivalent series resistance is 4.90 kΩ.
