Dhoot Transmission Computer Engineer Interview Questions and Answers

Q1. What is transformer?
Ans. 
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.

• When an AC current flows through the primary coil, it creates a magnetic field th...read more

Q2. What is ohm's law? Power formula?
Ans. 
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• The power formula is P = VI, where P is power, V is voltage, and I is current.

• Ohm's law is used to calculate the resistance of a circuit and to determine the amount of current flowing ...read more

Q1. Cement ka initial setting time
Ans. 
Initial setting time of cement is the time taken by cement to harden and resist penetration by a standard needle.
• Initial setting time is affected by factors like temperature, water-cement ratio, and type of cement.

• The standard needle used for testing has a diameter of 1.13 mm and a length of 50 mm.

• The initial setting time of ordinary Portland cement is around 30 minutes.

• The initial setting time of rapid hardening cemen
