  1. Question 1

    Q1. A 10 ohm resistor and a 20 ohm resistor are connected in series. What is the total resistance?

    • A) 10 ohm
    • B) 20 ohm
    • C) 30 ohm
    • D) 40 ohm

    Answer: 30 ohm

    Explanation: The total resistance in series is the sum of individual resistances, so R_total = 10 + 20 = 30 ohm. Option A is incorrect because it ignores the second resistor.
