Question

Accepted Answer

Answering technical questions related to power transformers, optical fibers, power factors, airplane speed measurement, and radar systems.

Power transformer works on the principle of electromagnetic induction to transfer electrical energy from one circuit to another.
Optical fibers work on the principle of total internal reflection of light to transmit data over long distances.
Power factor is the ratio of real power to apparent power and affects the efficiency of power transmission.
Airplane speed is measured in knots, which is equivalent to one nautical mile per hour.
Radar system uses radio waves to detect and locate objects, including aircraft, and can provide information on their position, speed, and direction.
Radar is used in aviation for air traffic control, weather monitoring, and collision avoidance systems.
