Q1. WHAT IS BLDC MOTOR
Ans. 
BLDC motor stands for Brushless DC motor, which is a type of electric motor that operates without the need for brushes to transfer electrical current.
• BLDC motors use electronic commutation instead of brushes to control the motor's operation.

• They are more efficient, reliable, and have a longer lifespan compared to brushed DC motors.

• BLDC motors are commonly used in applications such as electric vehicles, drones, and indu

Q1. Explain basic components in Electronics
Ans. 
Basic components in Electronics include resistors, capacitors, inductors, diodes, transistors, and integrated circuits.
• Resistors: Control the flow of electric current in a circuit.

• Capacitors: Store and release electrical energy.

• Inductors: Store energy in a magnetic field.

• Diodes: Allow current to flow in one direction only.

• Transistors: Amplify or switch electronic signals.

• Integrated Circuits: Combine multiple components

Q2. What is power and its units
Ans. 
Power is the rate at which work is done or energy is transferred. Its units are watts (W) in the International System of Units.
• Power is the amount of energy transferred or converted per unit time.

• The SI unit of power is the watt (W), which is equal to one joule per second.

• Other common units of power include horsepower (hp) and kilowatt (kW).

• Power can be calculated using the formula: Power = Work / Time
