Hitachi Astemo SMT Line Leader Interview Questions and Answers

Q1. Q.1. What is current?
Ans. 
Current refers to the flow of electric charge in a circuit.
• Current is measured in Amperes (A)

• It is the rate of flow of electric charge

• Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically

Q2. Q.2. What is transformer?
Ans. 
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two or more coils of insulated wire wrapped around a core

• Works on the principle of electromagnetic induction

• Used to increase or decrease voltage levels in electrical circuits

• Commonly used in power distribution systems

• Examples: step-up transformer, step-down transformer

Q3. Q.3 what is emf?
Ans. 
EMF stands for electromotive force, which is a measurement of the energy that causes current to flow in an electrical circuit.
• EMF is measured in volts and represents the potential difference between two points in a circuit.

• It is often associated with batteries and power sources that provide energy to electrical devices.

• EMF can be calculated using Ohm's Law, which relates voltage, current, and resistance in a circuit.

Q1. What is the full form of DC?
Ans. 
DC stands for Direct Current.
• DC is a type of electric current that flows in one direction.

• It is commonly used in batteries, electronic devices, and power transmission systems.

• DC is different from AC (Alternating Current), which periodically changes direction.

• Examples of DC-powered devices include smartphones, laptops, and electric vehicles.

Q2. What is the meaning of AC?
Ans. 
AC stands for Alternating Current.
• AC is an electric current that periodically reverses direction.

• It is commonly used in household electrical systems and power transmission.

• AC is generated by power plants and distributed through power lines.

• It is represented by a sinusoidal waveform.

• AC is different from DC (Direct Current) which flows in only one direction.

Q2. Refrigerator which type of current passing
Ans. 
The current passing through a refrigerator is alternating current (AC).
• Refrigerators use AC current to power their compressors and other electrical components.

• AC current periodically changes direction, allowing the refrigerator to cool and maintain a consistent temperature.

• AC current is supplied by the electrical outlet and converted to the appropriate voltage by the refrigerator's power supply.

• Unlike direct current (D...read more
