  1. Question 1

    Q1. A silicon diode has a voltage drop of 0.7 V when forward biased. What is the voltage drop across the diode when a 5 V battery is connected in series with the diode and a 1 kΩ resistor?

    • A) 0.7 V
    • B) 5 V
    • C) 4.3 V
    • D) 0 V

    Answer: 0.7 V

    Explanation: Voltage drop across diode remains 0.7 V as it is forward biased.
