Question: What is the equivalent resistance of three resistors, R1, R2, and R3, connected in series?

Options:

  1. R1 + R2 + R3
  2. 1/(1/R1 + 1/R2 + 1/R3)
  3. R1 * R2 * R3
  4. R1 - R2 - R3

Correct Answer: R1 + R2 + R3

Solution:

In a series connection, the total or equivalent resistance is the sum of the individual resistances.
