- Q4. Define transformer .
- Ans.
A transformer is a static device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two or more coils of insulated wire wound around a core
Primary coil receives electrical energy and induces a magnetic field in the core
Secondary coil receives the magnetic field and converts it back into electrical energy
Used to step up or step down voltage levels in power distrib

- Q6. Define flaming lept hand rule.
- Ans.
Flaming Lept Hand Rule is a rule used in electrical engineering to determine the direction of current flow in a conductor.
Flaming Lept Hand Rule is used to determine the direction of current flow in a conductor when the direction of magnetic field and motion of conductor are known.
It states that if the thumb, index finger, and middle finger of the right hand are extended in such a way that the thumb points in the direc...
- Q7. What is renewable energy and non renewable energy sources.
- Ans.
Renewable energy sources are sources of energy that are replenished naturally, such as sunlight, wind, and water. Non-renewable energy sources are sources that cannot be easily replenished, such as fossil fuels.
Renewable energy sources include solar power, wind power, hydropower, and geothermal energy
Non-renewable energy sources include coal, oil, and natural gas
Renewable energy is sustainable and environmentally frien...

- Q1. Probability of bit error in a binary symmetric channel
- Ans.
The probability of bit error in a binary symmetric channel can be calculated using the formula P = 1/2 * erfc(sqrt(Eb/N0)), where erfc is the complementary error function.
Probability of bit error in a binary symmetric channel is influenced by the signal-to-noise ratio (Eb/N0).
The error function erfc is used to calculate the probability of bit error.
The formula for calculating the probability of bit error is P = 1/2 * e

- Q5. If there are 200 fishes in an aquarium. 99% are red. How many fishes have to be removed to make the red fishes 98 % in the aquarium?
- Ans.
To make the red fishes 98%, 50 fishes have to be removed from the aquarium.
Calculate 1% of 200 fishes, which is 2 fishes.
To make the red fishes 98%, subtract 1% (2 fishes) from 99% (198 fishes).
To find the number of fishes to be removed, divide the difference by 1% (2 fishes).
Therefore, 50 fishes have to be removed to make the red fishes 98%.
Interview Preparation Tips
Experience: There were 40 aptitude questions of variable difficulty. More questions revolved around topics like time and work, distance, speed, time, profit loss, age etc.
