Final answer:
The total resistance in a series circuit is determined by summing up the individual resistance values of the resistors.
Step-by-step explanation:
In a series circuit, the total resistance is determined by summing up the individual resistance values of the resistors. The formula for calculating the total resistance in a series circuit is:
Total Resistance (Rtotal) = R₁ + R₂ + R₃ + ... + R
For example, if the values of the three resistors in a series circuit are 10 ohms, 20 ohms, and 30 ohms respectively, the total resistance would be:
Rtotal = 10 + 20 + 30 = 60 ohms
