Q1. Who is the home s law
Ans. 
Home's law is a principle that states that the current flowing through a conductor is directly proportional to the voltage applied across it.
• Home's law is also known as Ohm's law.

• It is expressed as I = V/R, where I is the current, V is the voltage, and R is the resistance.

• This law is fundamental to the study of electrical circuits and is used to calculate the behavior of circuits.

• For example, if the voltage across a re...read more

Q2. What is current unit?
Ans. 
The current unit is the ampere (A), which measures the flow of electric charge.
• The unit of electric current is the ampere (A).

• Current is the rate of flow of electric charge.

• It is measured using an ammeter.

• One ampere is equal to one coulomb of charge passing through a point in one second.

Q1. What is ohm law and current symble
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it.
• Ohm's law is expressed as V = I * R, where V is the voltage, I is the current, and R is the resistance.

• The current symbol is represented by the letter 'I'.

• Ohm's law is fundamental in understanding and analyzing electrical circuits.

• Example: If a circuit has a voltage of 12 volts and a resistance of 4 o...read more

Q1. Tow type of winding ?
Ans. 
The two types of winding in electrical engineering are lap winding and wave winding.
• Lap winding is used in DC machines and is characterized by multiple parallel paths for current flow.

• Wave winding is used in AC machines and is characterized by a single path for current flow.

• Lap winding provides high current capacity and low voltage output, while wave winding provides low current capacity and high voltage output.

• In lap ...read more

Q2. What is men by primary winding
Ans. 
The primary winding is the first coil in a transformer that receives electrical energy.
• The primary winding is typically connected to the power source.

• It is responsible for receiving and transmitting electrical energy to the secondary winding.

• The number of turns in the primary winding determines the voltage ratio between the primary and secondary sides.

• Primary windings are commonly found in transformers, induction motor

Q1. What do you no rotating part of machine
Ans. 
Rotating parts of a machine are components that move in a circular motion, such as motors, turbines, or fans.
• Rotating parts are typically components like motors, turbines, fans, or rotating shafts.

• Non-rotating parts include components like housings, casings, brackets, or stationary supports.

• Non-rotating parts are usually fixed in place and provide support or protection for the rotating components.

• Examples of non-rotati...read more
