Question: What is the equivalent resistance of three resistors of 2 ohms each connected in series? (2020)

Options:

Correct Answer: 6 ohms

Exam Year: 2020

Solution:

In series, the equivalent resistance is the sum of the individual resistances: R_eq = R1 + R2 + R3 = 2 + 2 + 2 = 6 ohms.

What is the equivalent resistance of three resistors of 2 ohms each connected in series? (2020)

Step 1: Identify the resistors. We have three resistors, each with a resistance of 2 ohms.
Step 2: Understand that when resistors are connected in series, the total or equivalent resistance is found by adding their resistances together.
Step 3: Write down 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 = 2 ohms + 2 ohms + 2 ohms.
Step 5: Perform the addition: 2 + 2 + 2 = 6 ohms.
Step 6: Conclude that the equivalent resistance of the three resistors in series is 6 ohms.
