Q1. Current (I) =voltage (V)/Resistance (R)
Ans. 
Ohm's Law states that current is equal to voltage divided by resistance.
• Ohm's Law is a fundamental principle in electrical engineering

• Current (I) is measured in Amperes (A)

• Voltage (V) is measured in Volts (V)

• Resistance (R) is measured in Ohms (Ω)

• The formula I = V/R can be used to calculate current in a circuit

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

Understand human differences, and gain knowledge about personality types. Attitude testing can be done directly or indirectly.

Group discussion (GD) is a comprehensive technique to judge the suitability of an individual and his appropriateness for admission, scholarship, job, etc. GD assesses the overall personality – thoughts, feelings and behaviour - of an individual in a group.

A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior.
