  1. Question 1

    Q1. A diode is connected in series with a 100 Ω resistor and a 12 V battery. If the voltage drop across the diode is 0.7 V, what is the current in the circuit?

    • A) 0.11 A
    • B) 0.113 A
    • C) 0.115 A
    • D) 0.12 A

    Answer: 0.113 A

    Explanation: Current = (12 - 0.7) / 100 = 0.113 A. Option A is incorrect due to rounding error.
