    What defines a diode?

    Formed by the junction of two semiconductors.

    What is the function of the anode in a diode?

    It allows current to flow when forward biased.

    What happens when a diode is reverse biased?

    It blocks current flow, acting as an insulator.

    How does temperature affect diode performance?

    Forward voltage decreases by 2 mV per degree Celsius.

    What is the significance of the saturation current (Is)?

    It depends on the doping levels of the semiconductors.

    What distinguishes forward bias from reverse bias in a diode?

    Forward bias allows current; reverse bias blocks it.

    What is the characteristic of a diode in forward bias?

    Current increases rapidly after a threshold voltage.

    What does the term 'blocking' refer to in diode operation?

    The state where the diode prevents current flow.

    What is the role of the Zener diode?

    It allows current to flow in reverse at a specified voltage.

    What is the purpose of filtering in diode circuits?

    To smooth out the output voltage after rectification.
