✍️ Sample BEE Questions & Answers

1. What does the term 'infinite bus' represent in power system analysis?

✓ A bus with constant voltage and frequency regardless of load

An infinite bus is an idealized source with constant voltage magnitude and frequency, used as a reference in stability studies.

2. The built-in potential (contact potential) of a p-n junction at thermal equilibrium is caused by:

✓ Diffusion of majority carriers and resulting charge separation

Diffusion of holes into the n-side and electrons into the p-side creates charge separation, establishing the built-in potential.

3. What is the output of a D flip-flop on the rising clock edge when D=0 and the current state Q=1?

✓ Q becomes 0

A D flip-flop samples D on the active clock edge and transfers it directly to Q, so Q becomes 0 regardless of the previous state.

4. In a 4-bit binary ripple counter, what is the maximum count value before it resets to zero?

✓ 15

A 4-bit counter counts from 0 to 2^4 − 1 = 15 before rolling over to zero.

5. In a series RLC circuit at resonance, which statement is correct?

✓ Impedance equals R only

At resonance, XL = XC, so they cancel and total impedance equals R alone.

6. What is the function of a priority encoder with inputs I0–I3?

✓ Outputs the binary code of the highest-priority active input

A priority encoder resolves simultaneous active inputs by outputting the binary code corresponding to the highest-priority (usually highest-numbered) active input.

What Practice Test Geeks adds beyond an AI chat for BEE

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

A timed, full-length BEE mock exam — 60 questions in 60 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
A fixed BEE question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
A printable BEE cheat sheet you can print or save as a PDF.
BEE flashcards built from the same question bank.
Free BEE practice tests with the correct answer shown after each question.
