Q.3 What is Artificial Intelligence? Mention its Applications:
Artificial Intelligence (AI) is the field of computer science that focuses on creating
machines or software that can perform tasks typically requiring human intelligence. These
tasks include learning, reasoning, problem-solving, language understanding, and vision.
Applications of AI:
Healthcare: AI is used for disease diagnosis, personalized treatment, and drug
discovery.
Finance: Fraud detection, automated trading, and customer support bots.
Automotive: Self-driving cars and driver-assistance systems.
Retail: Personalized recommendations, inventory management, and chatbots.
Manufacturing: Predictive maintenance, quality control, and automation.
Entertainment: Content recommendations (Netflix, YouTube), gaming, and film
production.

Q.5 Write the full form of RGB with its application:
RGB stands for Red, Green, Blue.
Application:
RGB is used in displays, such as computer monitors, TVs, and digital cameras, to
represent a broad spectrum of colors by combining red, green, and blue light in
varying intensities.
It is also applied in LED lighting systems to create customizable lighting colors.

Q.7 What is an IR Sensor and with examples:
IR Sensor (Infrared Sensor) is a device that detects infrared radiation (heat or light) from
objects in its environment. It works by emitting infrared light and detecting its reflection from
nearby objects.
Examples of IR Sensor:
Proximity Sensors: Used in smartphones for auto-screen turn-off during calls.
Motion Sensors: Used in security systems and automatic lighting systems.
Q.8 Explain the Function of LDR with Examples:
Function:
In low light, the resistance of the LDR is high, and in bright light, the resistance is
low.
This property is used to detect light levels in various applications.
Examples:
1. Automatic Street Lights: LDRs can be used in street lights to turn them on when it
gets dark and off when it's light.
2. Brightness Control in Devices: In devices like smartphones or TVs, LDRs adjust the
screen brightness based on ambient light.
Q.9 Write short notes on:
1. Pump Motor: A Pump Motor is an electric motor that drives a pump to move fluids
such as water, oil, or chemicals. The motor provides the mechanical energy needed to
circulate fluids in various systems like water pumps, oil pumps, and HVAC systems.
2. Servo Motor: A Servo Motor is a type of motor used for precise control of angular
position, velocity, and acceleration. It has an integrated feedback system, often using
an encoder or potentiometer, to provide accurate motion control. Commonly used in
robotics, CNC machines, and remote-controlled vehicles.
3. DC Motor: A DC Motor (Direct Current Motor) is an electric motor powered by a
direct current source. It converts electrical energy into mechanical motion. It is widely
used in small appliances, toys, and automotive applications due to its ease of control
and variable speed capabilities.
Q.10 Write short notes on:
1. LDR Sensor: An LDR (Light Dependent Resistor) is a type of sensor that changes
its resistance based on the amount of light falling on it. It has high resistance in the
dark and low resistance in the light. It is commonly used in light-sensitive
applications, like automatic street lighting or camera exposure control.
2. LED: An LED (Light Emitting Diode) is a semiconductor device that emits light
when current flows through it. LEDs are energy-efficient, long-lasting, and used in a
variety of applications, such as displays, lighting, and indicators in electronics.
3. RGB: RGB stands for Red, Green, and Blue, the three primary colors used in additive
color systems. By mixing different intensities of these three colors, a wide range of
colors can be produced. RGB is used in devices like monitors, TVs, and digital
cameras for color representation.
