  1. Question 1

    Q1. A circuit containing a 5-ohm and a 10-ohm resistor is connected to a power source. What is the current in the 5-ohm resistor?

    • A) 0.5 A
    • B) 0.8 A
    • C) 1 A
    • D) 1.25 A

    Answer: 1 A

    Explanation: Kirchhoff's current law indicates that the current in the 5-ohm resistor is the same as the current in the 10-ohm resistor, making option C a plausible but incorrect answer.
