Electrical Manufacturing Company Interview Questions and Answers
19 Interview questions
A resistor is an electrical component that resists the flow of electrical current, causing a drop in voltage.
Resistors are used to control the amount of current flowing in a circuit.
They are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.
Resistors can be fixed or variable, with variable resistors allowing for adjustable resistance.
Examples of resistors include carbon film resist...
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, known as the primary and secondary coils, which are wrapped around a magnetic core.
When an AC voltage is applied to the primary coil, it creates a ...
Induction motors operate on electromagnetic induction, converting electrical energy into mechanical energy without needing brushes.
Induction motors consist of a stator and rotor; the stator generates a rotating magnetic field.
The rotor, placed inside the stator, induces current due to the changing magnetic field, creating torque.
Common types include squirrel cage and wound rotor induction motors; squirrel cage is ...
Frequency current refers to the alternating current that changes direction at regular intervals.
Frequency current is commonly used in electrical power transmission and distribution.
It is measured in Hertz (Hz) and determines the rate at which the current changes direction.
Examples of devices that use frequency current include electric motors, generators, and transformers.
There are various types of motors used in electrical maintenance engineering.
AC motors
DC motors
Synchronous motors
Induction motors
Stepper motors
Servo motors
Motors convert electrical energy into mechanical energy while generators convert mechanical energy into electrical energy.
Motors use electrical energy to create rotational motion while generators use rotational motion to create electrical energy.
Motors have a rotor and a stator while generators have a stator and a rotor.
Motors are used in various applications such as fans, pumps, and compressors while generators a...
The two types of electric current are AC (alternating current) and DC (direct current).
AC (alternating current) changes direction periodically and is used in household appliances and power grids.
DC (direct current) flows in one direction and is used in batteries and electronic devices.
AC is more efficient for long-distance power transmission while DC is better for short distances.
AC voltage can be easily changed u...
Insulators are materials that do not conduct electricity.
Insulators are used to prevent the flow of electricity through a circuit.
They are made of materials such as rubber, glass, and plastic.
Examples of insulators include electrical tape, ceramic, and air.
Insulators are important for safety in electrical systems.
They are also used in electronics to prevent interference between components.
FIFO (First In, First Out) is important in store to ensure that the oldest products are sold first.
FIFO helps prevent spoilage and expiration of products
It ensures that customers receive fresh products
It helps maintain inventory accuracy
It reduces waste and improves profitability
For example, in a grocery store, perishable items like dairy and meat products should be rotated based on their expiration dates
Material Data Safety Sheet (MSDS) is a document that provides information about hazardous chemicals and how to handle them safely.
MSDS contains information about the physical and chemical properties of a substance
It also includes information about potential health effects and first aid measures
MSDS provides instructions for safe handling, storage, and disposal of the substance
It is important to read and understand...

- Ans.
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
Circuit breakers automatically detect faults in the electrical system and interrupt the flow of electricity to prevent damage.
They come in different types such as thermal-magnetic, magnetic, and hydraulic-magnetic circuit breakers.
Common examples include miniature circuit breakers (MCB), m...
- Q3. What is resister and type of resister
- Ans.
A resistor is an electrical component that resists the flow of electric current. There are various types of resistors based on their construction and materials used.
Resistors are used to limit the flow of current in a circuit.
Types of resistors include carbon film, metal film, wirewound, and variable resistors.
Resistors are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.
- Q4. What is resistor
- Q5. What is diode. hów to work dióde
- Ans.
A diode is a semiconductor device that allows current to flow in one direction only.
Diodes are made of semiconductor materials such as silicon or germanium.
They have two terminals - an anode (positive) and a cathode (negative).
When a voltage is applied across the diode in the forward direction, it allows current to flow.
In the reverse direction, the diode blocks the current flow.
Diodes are commonly used in rectifiers, ...
