Question

    The device which transfer the signal from low

    resistance region to high resistance region is –
    A diode Correct Answer Incorrect Answer
    B transistor Correct Answer Incorrect Answer
    C capacitor Correct Answer Incorrect Answer
    D inductor Correct Answer Incorrect Answer

    Solution

    A transistor transfers a signal from a low resistance to high resistance. It has two PN-junctions: one junction is forward biased and other junction is reverse biased having low resistance path and high resistance pathrespectively.Theweaksignalisintroduced in the lowresistance, circuit and output is taken from the high resistance circuit.
