Ans. 
A diode is a semiconductor device that allows current to flow in one direction only. AC can be converted to DC using rectifiers. Microprocessors process data using logic circuits. Transistors amplify or switch electronic signals. AC motors run on alternating current while DC motors run on direct current. Power supplies can work with both AC and DC inputs. Resistance is the opposition to the flow of electric current. Re...read more

Q2. How to work relay,
Ans. 
Relays are electrically operated switches used to control high power devices with low power signals.
• Relays consist of a coil, an armature, and one or more contacts.

• When current flows through the coil, it creates a magnetic field that attracts the armature, closing the contacts.

• Relays are commonly used in control circuits to switch high power devices such as motors, lights, and heaters.

• They can be used to isolate contro...read more

Q2. What is annealing
Ans. 
Annealing is a heat treatment process used to reduce hardness and increase ductility of a material.
• Annealing involves heating a material to a specific temperature and then slowly cooling it down.

• This process helps to relieve internal stresses, improve machinability, and enhance electrical conductivity.

• Common examples include steel annealing to improve its ductility and copper annealing to increase its conductivity.

Q3. What is tempring
Ans. 
Tempering is a heat treatment process used to improve the toughness and ductility of metals by reducing internal stresses.
• Tempering involves heating the metal to a specific temperature and then cooling it in a controlled manner.

• The process helps to reduce the hardness of the metal while increasing its toughness and ductility.

• Commonly used in the production of steel to achieve the desired balance of strength and flexibi...read more

Q1. Basic principles of all instruments
Ans. 
Instruments operate on principles of measurement, calibration, and signal processing to provide accurate data.
• Measurement: Instruments quantify physical properties (e.g., thermometers measure temperature).

• Calibration: Ensures accuracy by comparing instrument readings to known standards (e.g., calibrating a scale).

• Signal Processing: Converts raw data into usable information (e.g., oscilloscopes display electrical signal...read more

Q2. How to resolved the problem in different situations
Ans. 
Effective problem resolution requires a systematic approach tailored to the situation's specifics.
• Identify the problem: Gather information to understand the issue clearly. For example, if a machine is malfunctioning, check error logs.

• Analyze the situation: Determine the root cause by asking 'why' multiple times. If a server is down, investigate recent changes or updates.

• Develop a solution: Brainstorm potential fixes an...read more
