  1. 1. A Zener shunt regulator has a 15 V DC supply, a 200 Ω series resistor and an ideal 6 V Zener diode (zero Zener resistance) in parallel with a 1 kΩ load. What is the current through the Zener diode?

    • a. 51 mA
    • b. 39 mA
    • c. 45 mA
    • d. 6 mA
  2. 2. An npn BJT has β = 150 and is biased at a collector current of 0.5 mA. Take the thermal voltage V_T = 25 mV. What is its small-signal input resistance r_π, in kΩ? Give the answer rounded off to one decimal place.

    FAQ

    How many Analog Circuits questions come in GATE EC?
    Analog Circuits is part of the Analog Circuits section (see the pattern questions in the section). Its share varies by paper; our tests give 15 per test so one topic is drilled at a time.
    Are the GATE EC Analog Circuits questions free?
    The first Analog Circuits test is free, with solutions. Later tests come with any GATE EC pass or ₹9 each.
    How should I practise Analog Circuits for GATE EC?
    Take one timed test, read every solution (right answers included), note the method you missed, then take the next test two days later. Compare with your Analog Circuits score in a full mock to see if the topic still costs marks.
