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

Options:

Correct Answer: 15 Ω

Solution:

Total resistance in series is R_total = R1 + R2 = 10 Ω + 5 Ω = 15 Ω.

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

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

Step 1: Identify the resistors in the circuit. We have a 10 Ω resistor and a 5 Ω 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_total = R1 + R2.
Step 4: Substitute the values of the resistors into the formula: R_total = 10 Ω + 5 Ω.
Step 5: Perform the addition: 10 Ω + 5 Ω = 15 Ω.
Step 6: Conclude that the total resistance is 15 Ω.

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