The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.
Entropy always increases in a closed system
Heat flows from hot to cold objects
Efficiency of energy conversion processes is limited by the second law
Examples: a cup of hot coffee cooling down, a car engine losing energy as heat
Strength of material refers to the ability of a material to withstand applied forces without failing.
Strength of material is typically measured in terms of tensile strength, yield strength, and ultimate strength.
Different materials have different strengths - for example, steel is stronger than aluminum.
Factors affecting strength include material composition, manufacturing process, and environmental conditions.
Strength ...

Decarburization (decarb) is a process in which carbon is removed from the surface of stainless steel during the Argon Oxygen Decarburization (AoD) process.
Decarburization occurs when carbon in the stainless steel reacts with oxygen to form carbon monoxide gas, which then escapes from the steel.
This process can lead to a decrease in carbon content at the surface of the steel, affecting its mechanical properties.
Decarbur...
I applied via AmbitionBox and was interviewed in Aug 2024. There were 3 interview rounds.
Voltage is the measure of electrical potential difference, while current is the flow of electric charge.
Voltage is measured in volts (V) and represents the potential difference between two points in a circuit
Current is measured in amperes (A) and represents the flow of electric charge through a circuit
Ohm's Law relates voltage, current, and resistance: V = I * R
Voltage sources include batteries, power supplies, and gen...
Analog signals are continuous, varying in amplitude and frequency. Digital signals are discrete, represented by binary numbers.
Analog signals have infinite possible values within a range
Digital signals have only two possible values, 0 and 1
Examples of analog signals include sound waves and light waves
Examples of digital signals include computer data and CDs
Electrical engineering deals with the study and application of electricity, electronics focuses on the study of electronic components and systems.
Electrical engineering involves the generation, distribution, and utilization of electrical power.
Electronics focuses on the design and development of electronic circuits, devices, and systems.
Examples of electrical engineering include power generation plants, transmission li...
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 and a cathode.
When a positive voltage is applied to the anode and a negative voltage to the cathode, the diode conducts electricity.
Diodes are commonly used in rectifiers, voltage regulators, and signal demodulation.
Examples of dio...
Ohm's law formula relates voltage, current, and resistance in an electrical circuit.
Ohm's law formula is V = I * R
V represents voltage in volts
I represents current in amperes
R represents resistance in ohms
The formula can be rearranged to solve for different variables, such as I = V / R or R = V / I

Iron ore is a mineral substance which, when heated in the presence of a reductant, yields metallic iron (Fe).
Iron ore is typically composed of iron oxides and may contain varying amounts of other minerals such as silicon, aluminum, and phosphorus.
The chemical composition of iron ore varies depending on the type of ore and the mining location.
Hematite and magnetite are the two most common types of iron ore, with the for...
