Medhaj Techno Concept Interview Questions, Process, and Tips

What will be the turns ratio if a certain transformer has 400 turns in the primary winding and 2,000 turns in the secondary winding?

Q1. What is the impact on phase angle when the frequency of the voltage applied to a series RC circuit is increased?
Ans. 
Phase angle decreases as frequency increases in a series RC circuit.
• As frequency increases, the capacitive reactance decreases, leading to a decrease in phase angle.

• At low frequencies, the capacitive reactance is high, causing a larger phase angle.

• At high frequencies, the capacitive reactance is low, resulting in a smaller phase angle.

Q2. If the frequency of the voltage applied to a series RC circuit is increased, the phase angle decreases.
Ans. 
Yes, as the frequency of the voltage applied to a series RC circuit is increased, the phase angle decreases.
• Increasing frequency means the reactance of the capacitor decreases, leading to a decrease in the phase angle.

• At very high frequencies, the capacitor acts like a short circuit, causing the phase angle to approach zero.

• This phenomenon is important in AC circuits and signal processing applications.

Q1. The minimum clearance between the ground and a 220 Kv line is about -7 mtr
Ans. 
The minimum clearance between the ground and a 220 Kv line is approximately -7 meters.
• The negative clearance of -7 meters indicates that the 220 Kv line is below ground level.

• This clearance is important to prevent any contact between the line and the ground or any structures.

• Proper clearance ensures safety and prevents electrical hazards.

• Example: If the ground level is at 0 meters, the 220 Kv line would be 7 meters bel

Q2. The spacing between phase conductor of a 220 Kv lion approximately equal to-6 mtr
Ans. 
The spacing between phase conductors of a 220 kV line is approximately 6 meters.
• The spacing between phase conductors is crucial for maintaining safety and efficiency in power transmission.

• Proper spacing helps prevent electrical arcing and ensures reliable operation of the transmission line.

• In the case of a 220 kV line, a spacing of around 6 meters is commonly used to meet safety standards and minimize interference betw
