Q1. What is behaviour ?
Ans. 
Behaviour refers to the way in which a person or animal acts or conducts themselves in response to a particular situation or stimulus.
• Behaviour is influenced by genetics, environment, and past experiences.

• It can be observed and measured through actions, reactions, and responses.

• Behaviour can be categorized as either innate (instinctual) or learned.

• Examples of behaviour include aggression, shyness, curiosity, and friend

Q2. What is the best method in power transfers?
Ans. 
The best method in power transfers is through high voltage transmission lines.
• High voltage transmission lines are more efficient in transferring power over long distances.

• Using transformers to step up the voltage before transmission and step down the voltage at the receiving end helps minimize power loss.

• HVDC (High Voltage Direct Current) transmission is another efficient method for long distance power transfers.

Q1. What is current
Ans. 
Current is the flow of electric charge through a conductor.
• Current is measured in Amperes (A)

• It is the rate of flow of electric charge

• Current can be either direct current (DC) or alternating current (AC)

• Examples: A light bulb connected to a power source has current flowing through it

• In a circuit, current flows from the positive terminal of the voltage source to the negative terminal

Q2. What are the method to convert in inverter
Ans. 
Methods to convert inverter include pulse width modulation, sine wave modulation, and square wave modulation.
• Pulse width modulation (PWM) is a common method used to convert inverter signals by varying the width of the pulses.

• Sine wave modulation involves generating a sine wave signal to mimic the output of an inverter.

• Square wave modulation produces a square wave output by switching between high and low voltage levels.

Q2. What it ohm's law
Ans. 
Ohm's law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points.
• Ohm's law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• It is named after German physicist Georg Simon Ohm.

• Ohm's law is fundamental in the field of electrical engineering and is used to analyze and design electrical circuits.

Q4. Difference between AC and DC
Ans. 
AC stands for alternating current, which changes direction periodically, while DC stands for direct current, which flows in one direction.
• AC changes direction periodically, while DC flows in one direction constantly.

• AC is used in household appliances and power distribution, while DC is used in batteries and electronic devices.

• AC can be easily converted to different voltage levels using transformers, while DC requires m...read more

Q5. How will you calculate current carrying in a conductor ?
Ans. 
Current carrying in a conductor can be calculated using Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R).
• Use Ohm's Law: I = V / R

• Determine the voltage across the conductor

• Find the resistance of the conductor

• Calculate the current flowing through the conductor using the formula
