TVS Motor Electrical Engineer Interview Questions and Answers

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 resistor is increased, the current through it will also incr...read more

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 ohms, the current flowing through the circuit would be 3 am...read more

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 motors, and other electrical devices.

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.

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 winding, the number of parallel paths is equal to the numb...read more
