  1. Question 1

    Q1. A 2 ohm resistor is connected in parallel with a 4 ohm resistor. What is their equivalent resistance?

    • A) 1 ohm
    • B) 4/3 ohm
    • C) 8/6 ohm
    • D) 6 ohm

    Answer: 4/3 ohm

    Explanation: Using the formula for parallel resistors, 1/R_eq = 1/2 + 1/4 = 3/4, so R_eq = 4/3 ohm. Option A is incorrect because it incorrectly calculates the equivalent resistance.
