Q1. What id diode ?
Ans. 
A diode is an electronic component that allows current to flow in one direction and blocks it in the opposite direction.
• Diodes are made of semiconductor materials, such as silicon or germanium.

• They have two terminals: an anode (positive terminal) and a cathode (negative terminal).

• When a diode is forward-biased, it allows current to flow through it.

• When a diode is reverse-biased, it blocks the current.

• Diodes are commonl...read more

Q2. Draw the diagram of diode
Ans. 
A diode is a two-terminal electronic component that allows current to flow in one direction and blocks it in the opposite direction.
• A diode has an anode and a cathode terminal.

• It is represented by a triangle with a line at the base.

• The arrowhead of the triangle points towards the cathode terminal.

• The line at the base represents the anode terminal.

• The symbol of a diode is often accompanied by its part number or label.

Q3. Compare conductor insulator semiconductor
Ans. 
Conductor, insulator, and semiconductor are materials with different electrical conductivity properties.
• Conductor: Materials that allow the flow of electric current easily. Examples: copper, aluminum.

• Insulator: Materials that do not allow the flow of electric current. Examples: rubber, glass.

• Semiconductor: Materials with intermediate conductivity. Examples: silicon, germanium.

Q1. What is the relationship between a servo motor and its drive?
Ans. 
A servo motor is controlled by a drive that regulates its speed, position, and torque for precise motion control.
• A servo motor provides precise control of angular or linear position, velocity, and acceleration.

• The drive acts as the interface between the motor and the control system, sending commands to the motor.

• For example, in robotics, a servo motor adjusts the position of a robotic arm based on the drive's input.

• The...read more

Q2. What does the term VFD refer to?
Ans. 
VFD stands for Variable Frequency Drive, a device used to control the speed and torque of electric motors.
• VFDs adjust the frequency and voltage supplied to an electric motor.

• They improve energy efficiency by matching motor speed to load requirements.

• Commonly used in HVAC systems, conveyor belts, and pumps.

• Example: A VFD can reduce the speed of a fan during low demand periods.

Q2. Whai is hooks law
Ans. 
Hooke's Law states that the force exerted by a spring is directly proportional to its extension or compression.
• Hooke's Law formula: F = kx, where F is the force, k is the spring constant, and x is the displacement.

• Example: If a spring has a spring constant of 10 N/m and is stretched by 2 meters, the force exerted is 20 N.

• The law applies to elastic materials within their elastic limit, beyond which they may deform perma...read more
