Question: If two resistors of 4Ω and 6Ω are connected in series, what is the total resistance? (2023)

Options:

Correct Answer: 10Ω

Exam Year: 2023

Solution:

In series, R_eq = R1 + R2 = 4Ω + 6Ω = 10Ω.

If two resistors of 4Ω and 6Ω are connected in series, what is the total resistance? (2023)

Step 1: Identify the resistors. We have two resistors: one is 4 ohms (Ω) and the other is 6 ohms (Ω).
Step 2: Understand that when resistors are connected in series, you add their resistances together.
Step 3: Write down the formula for total resistance in series: R_eq = R1 + R2.
Step 4: Substitute the values of the resistors into the formula: R_eq = 4Ω + 6Ω.
Step 5: Perform the addition: 4 + 6 = 10.
Step 6: Conclude that the total resistance is 10 ohms (Ω).

Series Resistance Calculation – In a series circuit, the total resistance is the sum of the individual resistances.
