  • The primary winding is connected to the in...

A Diploma Trainee Engineer was asked
Q. What is a resistor in electronics?
Ans. 

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 resisto...

A Diploma Trainee Engineer was asked
Q. Newtons law of motion
Ans. 

Newtons law of motion describes the relationship between an object and the forces acting upon it.

  • First law states that an object at rest will remain at rest and an object in motion will remain in motion with a constant velocity unless acted upon by an unbalanced force.

  • Second law states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.

  • Thir...

A Diploma Trainee Engineer was asked
Q. Which type of satellite communication
Ans.

Can speak English, can’t deliver in interviews
I feel like I can't speak fluently during interviews. I do know english well and use it daily to communicate, but the moment I'm in an interview, I just get stuck. since it's not my first language, I struggle to express what I actually feel. I know the answer in my head, but I just can’t deliver it properly at that moment. Please guide me
