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. 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.

- 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.
