Speed and feed formula is used in machining to determine the optimal cutting parameters for a specific material and tool.
Speed and feed formula calculates the spindle speed (RPM) and feed rate (IPM) for a given material and tool combination.
The formula takes into account factors such as material type, tool diameter, and desired surface finish.
For example, the formula for calculating spindle speed is: RPM = (CS x 4) / D...

Leakage current in CMOS refers to the small amount of current that flows through the transistors when they are in the off state.
Leakage current occurs due to the imperfect insulation between the source and drain terminals of the transistors.
It is an undesirable phenomenon as it leads to power dissipation and can affect the performance and reliability of CMOS circuits.
Leakage current can be categorized into subthreshold...
The different terminals of a MOSFET are the gate, source, and drain.
The gate terminal controls the flow of current between the source and drain.
The source terminal is where the current enters the MOSFET.
The drain terminal is where the current exits the MOSFET.
The gate-source voltage determines the conductivity of the channel between the source and drain.
Examples of MOSFETs include enhancement-mode and depletion-mode MO
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.
Ohm's law is expressed as V = IR, where V is the voltage, I is the current, and R is the resistance.
It helps in understanding the relationship between voltage, current, and resistance in an electrical circuit.
For example, if the voltage across a resistor is...
The direction of current flow is opposite to the direction of electron flow due to historical convention.
The concept of current flow was developed before the discovery of electrons.
Benjamin Franklin proposed the convention of positive charge carriers, which led to the opposite direction of current flow.
In reality, electrons are negatively charged and flow from the negative terminal to the positive terminal of a power s...
An inductor is a passive electronic component that stores energy in a magnetic field when current flows through it.
Inductors are typically made of a coil of wire wound around a core material.
They are used in electronic circuits to control the flow of current and store energy.
Inductors can be found in various applications such as power supplies, filters, and oscillators.
They are measured in units called henries (H).
Indu...
A wire harness is a collection of wires, cables, and connectors that transmit electrical signals and power between different components in a system.
Wire harnesses provide a neat and organized way to route and protect wires in a system.
They ensure proper connectivity and prevent wire damage or short circuits.
Wire harnesses simplify troubleshooting and maintenance by allowing easy identification and replacement of faulty...
Sputtering is a process used in manufacturing to deposit thin films of material onto a surface.
Sputtering is a physical vapor deposition technique.
It involves bombarding a target material with high-energy ions or atoms.
This bombardment dislodges atoms from the target material, which then deposit onto a substrate.
Sputtering is commonly used in the production of semiconductor devices, solar cells, and thin film coatings.

I applied via Approached by Company and was interviewed before Jun 2022. There were 5 interview rounds.
Sub cooling in air conditioning is the process of cooling the refrigerant below its saturation temperature to improve system efficiency.
Sub cooling increases the efficiency of the air conditioning system by ensuring the refrigerant is in a liquid state before entering the expansion valve.
It helps in preventing flash evaporation of the refrigerant, which can lead to inefficiencies in the system.
Sub cooling is typically ...
ISEER rating is calculated based on the weighted average of the cooling performance of an air conditioner under different conditions.
ISEER = (Weighted Cooling Capacity at 100% load x 0.4) + (Weighted Cooling Capacity at 75% load x 0.2) + (Weighted Cooling Capacity at 50% load x 0.4)
The higher the ISEER rating, the more energy efficient the air conditioner is.
ISEER rating helps consumers compare the energy efficiency of...
The refrigeration cycle is a thermodynamic cycle used in refrigerators and air conditioning systems to transfer heat from a low temperature to a high temperature environment.
The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The refrigerant enters the compressor as a low-pressure gas and leaves as a high-pressure, high-temperature gas.
The high-pressure gas then flows into...
Mainstream refrigerants used in household air conditioning include R-410A, R-22, and R-134a.
R-410A is a popular refrigerant known for its high efficiency and environmental friendliness.
R-22, although being phased out due to its ozone-depleting properties, is still commonly found in older air conditioning systems.
R-134a is commonly used in automotive air conditioning systems but can also be found in some household units
1 ton cooling concept refers to the amount of heat required to melt one ton of ice in a 24-hour period.
1 ton of cooling is equal to 12,000 BTUs per hour
It is commonly used in the HVAC industry to measure the cooling capacity of air conditioning systems
For example, a 2-ton air conditioner can remove 24,000 BTUs of heat per hour
The relationship between current, voltage, and power is described by Ohm's Law, which states that current is directly proportional to voltage and inversely proportional to resistance.
Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.
Power (P) is calculated using the formula P = V * I, where P is power, V is voltage, and I is current.
In a circuit with a constant resistance, an increa...
