What is the equivalent resistance of three resistors, 2Ω, 3Ω, and 6Ω, connected in series?
Correct Answer: 11Ω
Step 1: Identify the resistors and their values. We have three resistors: R1 = 2Ω, R2 = 3Ω, and R3 = 6Ω.
Step 2: Understand that when resistors are connected in series, the total or equivalent resistance (R_eq) is found by adding their individual resistances together.
Step 3: Write the formula for equivalent resistance in series: R_eq = R1 + R2 + R3.
Step 4: Substitute the values of the resistors into the formula: R_eq = 2Ω + 3Ω + 6Ω.
Step 5: Perform the addition: 2 + 3 = 5, then 5 + 6 = 11.
Step 6: Conclude that the equivalent resistance of the three resistors in series is 11Ω.
