Assystem Junior Engineer Interview Questions and Answers

Impedance is the total opposition to the flow of alternating current in a circuit, while reactance is the opposition to the flow of alternating current caused by capacitance or inductance.

• Impedance is a combination of resistance and reactance in a circuit.

• Reactance is the opposition to the flow of alternating current caused by capacitance or inductance.

• Capacitive reactance is the opposition to the flow of alternating c...read more

Plant load factor is calculated by dividing the actual energy generated by the maximum possible energy that could have been generated.

• Plant load factor = Actual energy generated / Maximum possible energy that could have been generated

• Maximum possible energy is calculated by multiplying the rated capacity of the plant with the number of hours in a given time period

• Plant load factor is expressed as a percentage

• It is used...read more

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

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
