Interview Questions and Answers

A resistor is an electronic component that limits the flow of electric current in a circuit.

• Resistors are used to control the amount of current flowing through a circuit.

• They are passive components that dissipate energy in the form of heat.

• Resistors are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.

• They can be fixed resistors with a specific resistance value or variable resistors that can be adjusted.

• Resistors are commonly used in voltage ...read more

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease the voltage levels in electrical power transmission and distribution systems.

• They consist of two or more coils of wire, known as windings, which are wound around a core made of magnetic material.

• The primary winding is connected to the input voltage source, while the secondary winding is connected to...read more

There are two types of satellite communication: geostationary and low earth orbit.

• Geostationary satellites are placed at a fixed point above the earth's equator and are used for TV broadcasting, weather forecasting, and military communication.

• Low earth orbit satellites are placed closer to the earth's surface and are used for GPS, satellite phones, and remote sensing.

• Satellite communication is important for global connectivity and communication.
