Q2. What is the difference between PNP AND NPN Transistor?
PNP and NPN transistors are two types of bipolar junction transistors with opposite polarity.
PNP has a layer of N-type semiconductor sandwiched between two layers of P-type semiconductor, while NPN has a layer of P-type semiconductor sandwiched between two layers of N-type semiconductor.
In PNP, the current flows from the emitter to the base and then to the collector, while in NPN, the current flows from the emitter to the collector through the base.
PNP is used in high-side sw...read more
Q3. What is full form of cnc
Computer Numerical Control
Stands for Computer Numerical Control
Used in manufacturing processes to control machining tools and equipment
Automates the operation of machines based on pre-programmed sequences of commands
Examples include CNC milling machines, CNC routers, CNC lathes
Q4. How many type of valves studying in Hydraulics systems?
There are various types of valves used in hydraulic systems.
There are directional control valves, pressure control valves, flow control valves, and check valves.
Directional control valves control the direction of fluid flow.
Pressure control valves regulate the pressure of the fluid.
Flow control valves regulate the flow rate of the fluid.
Check valves allow fluid to flow in one direction only.
Other types of valves include relief valves, sequence valves, and throttle valves.
Q5. Comment name of Linear Integrated circuit
Operational Amplifier (Op-Amp) is a popular Linear Integrated Circuit.
Op-Amp is used in various applications such as amplifiers, filters, oscillators, comparators, etc.

Op-Amps can be used in both inverting and non-inverting configurations.
Q6. What is plc? Describe NO & NC actuation state?
PLC stands for Programmable Logic Controller. NO and NC are actuation states used in electrical circuits.
PLC is a digital computer used to automate industrial processes.
NO stands for Normally Open and NC stands for Normally Closed.
In NO state, the circuit is open when the device is not activated.
In NC state, the circuit is closed when the device is not activated.
NO and NC are used in electrical circuits to control the flow of current.
Examples of devices that use NO and NC sta...read more
Q7. What is types of break
Types of breaks include mechanical breaks, hydraulic breaks, and electromagnetic breaks.
Mechanical breaks rely on friction to slow down or stop motion, such as brake pads on a bicycle.
Hydraulic breaks use fluid pressure to transfer force, commonly found in car braking systems.
Electromagnetic breaks use electromagnetic force to slow down or stop motion, often used in industrial machinery.

Q11. What is the use of capacitor?
Capacitor is an electronic component that stores electrical energy in an electric field.
Used in power supply circuits to filter out noise and ripple
Used in timing circuits to control the rate of oscillation
Used in audio circuits to filter out unwanted frequencies
Used in motor starting circuits to provide a boost of power
Examples: camera flash, air conditioner, radio receiver
Q12. What is force ,types
Force is a push or pull acting upon an object resulting from its interaction with another object.
Force is a vector quantity, meaning it has both magnitude and direction.
Types of forces include gravitational force, electromagnetic force, frictional force, tension force, and normal force.
For example, when you push a door to open it, you are applying a force in the direction of the door.
Another example is the force of gravity pulling objects towards the Earth.
Q13. What is cnc operator
A CNC operator is a skilled professional who operates computer numerical control machines to perform various tasks like cutting, shaping, and finishing materials.
CNC operators use computer programs to control and operate machines for tasks like drilling, milling, and turning.
They interpret blueprints, set up machines, and monitor the production process to ensure accuracy and efficiency.
CNC operators are responsible for maintaining and troubleshooting machines to ensure smooth...read more
Q14. What is Quality
Quality refers to the degree of excellence or superiority of a product or service.
Quality is the measure of how well a product or service meets the expectations and requirements of customers.
It involves meeting or exceeding standards and specifications.
Quality can be subjective and may vary based on individual preferences and needs.
Quality can be assessed through various methods such as inspections, testing, and customer feedback.
