Question: If a 5Ω resistor is connected in series with a 10Ω resistor, what is the total resistance? (2022)

Options:

Correct Answer: 15Ω

Exam Year: 2022

Solution:

In series, R_eq = R1 + R2 = 5Ω + 10Ω = 15Ω.

If a 5Ω resistor is connected in series with a 10Ω resistor, what is the total resistance? (2022)

If a 5Ω resistor is connected in series with a 10Ω resistor, what is the total resistance? (2022)

Step 1: Identify the resistors in the circuit. We have a 5Ω resistor and a 10Ω resistor.
Step 2: Understand that when resistors are connected in series, the total resistance is the sum of the individual resistances.
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 = 5Ω + 10Ω.
Step 5: Perform the addition: 5Ω + 10Ω = 15Ω.
Step 6: Conclude that the total resistance is 15Ω.

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