Question: A 5 ohm resistor and a 10 ohm resistor are connected in series. What is the total resistance?

Options:

Correct Answer: 15 ohms

Solution:

In series, the total resistance is R_total = R1 + R2 = 5 + 10 = 15 ohms.

A 5 ohm resistor and a 10 ohm resistor are connected in series. What is the total resistance?

A 5 ohm resistor and a 10 ohm resistor are connected in series. What is the total resistance?

Correct Answer: 15 ohms

Step 1: Identify the resistors in the circuit. We have a 5 ohm resistor and a 10 ohm 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 = 5 ohms + 10 ohms.
Step 5: Perform the addition: 5 + 10 = 15 ohms.
Step 6: Conclude that the total resistance of the circuit is 15 ohms.

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