Question: What is the equivalent resistance of two resistors of 10 ohms and 20 ohms connected in series?

Options:

Correct Answer: 30 ohms

Solution:

In series, the equivalent resistance R_eq = R1 + R2 = 10 ohms + 20 ohms = 30 ohms.

Correct Answer: 30 ohms

Step 1: Identify the resistors. We have two resistors: one is 10 ohms (R1) and the other is 20 ohms (R2).
Step 2: Understand that when resistors are connected in series, you add their resistances together.
Step 3: Write the formula for equivalent resistance in series: R_eq = R1 + R2.
Step 4: Substitute the values of R1 and R2 into the formula: R_eq = 10 ohms + 20 ohms.
Step 5: Perform the addition: 10 ohms + 20 ohms = 30 ohms.
Step 6: Conclude that the equivalent resistance of the two resistors in series is 30 ohms.
