Q2. Stainless steel AoD process what happened in decarb
Ans. 
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...read more

Q1. Define the voltage and current
Ans. 
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...read more

Q4. Define the diode and semiconductor devices
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 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...read more

Q5. Define the ohm’s law formula
Ans. 
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
