Junior Technician Interview Questions and Answers for Freshers
Q1. How to calculate for the resistance
Resistance can be calculated using Ohm's Law, which states that resistance is equal to voltage divided by current.
Use Ohm's Law: R = V / I
Resistance is measured in ohms (Ω)
Voltage is measured in volts (V)
Current is measured in amperes (A)
Example: If the voltage is 12V and the current is 2A, the resistance would be 6Ω
Q2. What is embedded system
Embedded system is a computer system designed to perform specific tasks, with dedicated functions and limited resources.
Embedded systems are found in various devices such as smartphones, cars, medical equipment, and home appliances.
They are designed to be reliable, efficient, and often operate in real-time.
Embedded systems typically consist of a microcontroller or microprocessor, memory, input/output interfaces, and software.
They can be programmed in various languages like C,...read more
Q3. What is embedded system usefull
Embedded systems are useful for controlling and monitoring various devices and systems.
Embedded systems are used in a wide range of applications such as consumer electronics, automotive systems, industrial automation, and medical devices.
They provide real-time control and monitoring capabilities, allowing devices to respond quickly and accurately to external events.
Embedded systems are often used in safety-critical applications where reliability and stability are crucial.

Q4. What is colour coding
Colour coding is a system of assigning colours to objects or information to convey meaning or identification.
Used in various fields such as electronics, wiring, and safety equipment
Example: Red wire indicates positive polarity in electronics
Example: Red colour on safety equipment indicates fire hazard
Helps in quick identification and reduces errors
Q5. Aircraft fuelling procedure and precautions
Aircraft fuelling involves a series of procedures and precautions to ensure safety and efficiency.
Before fuelling, the aircraft must be properly grounded to prevent static electricity buildup.
The fuel truck must be positioned correctly and securely connected to the aircraft's fuel system.
The fuel type and quantity must be verified before starting the fuelling process.
During fuelling, the fuel flow rate must be monitored to prevent overfilling or spillage.
After fuelling, the f...read more
Q6. Colours coding for the resistance
Color coding is used to identify the resistance value of a resistor.
The first band represents the first digit of the resistance value.
The second band represents the second digit of the resistance value.
The third band represents the multiplier.
The fourth band represents the tolerance.
For example, a resistor with brown, black, red, and gold bands has a resistance value of 1.0 ohm with a tolerance of +/- 5%.

Q7. Aircraft transit procedure
Aircraft transit procedure involves the movement of an aircraft from one location to another.
The aircraft is inspected for any damages or issues before transit.
The fuel and oil levels are checked and topped up if necessary.
The cargo and baggage are loaded onto the aircraft.
The passengers are boarded onto the aircraft.
The pilot performs pre-flight checks and obtains clearance for takeoff.
The aircraft is guided to the runway and takes off.
During transit, the pilot communicates ...read more
