    Q1. Which formula correctly expresses Ohm's law?

    • A) V = IR
    • B) V = I/R
    • C) V = I + R
    • D) V = I - R

    Answer: V = IR

    Explanation: Ohm's law states that voltage equals current multiplied by resistance at constant temperature. The other formulas do not match the defined relationship between V, I, and R.
