  1. Question 1

    Q1. A wire of length l and resistance R is divided into 10 equal parts. The resistance of each part is

    • A) R / 10
    • B) R / 100
    • C) 10R
    • D) 100R

    Answer: R / 10

    Explanation: Using R = ρl / A, when l is divided by 10, R is also divided by 10, hence R / 10
