Physics Lab Experiments: Electricity and Magnetism
Activity: Magnetic Field Near Current-Carrying Conductor
To observe the deflection of a magnetic needle placed near a conductor carrying current.
Apparatus and Materials:
Magnetic needle, battery, ammeter, rheostat, key, conducting wire, etc.
Theory:
When electric current passes through a conductor, a magnetic field is produced around it.
Procedure:
- Remove magnetic substances from the table and place the magnetic needle on it. Connect the cell, rheostat, key, and ammeter in series with the experimental
Fundamentals of Technology and Basic Electronics
1. What Is Technology?
Technology is the application of knowledge and skills to solve problems and satisfy human needs.
Technology helps people create objects and systems that make life easier, such as machines, tools, transport, and communication devices.
Technology uses:
- Scientific and technical knowledge
- Technical skills
- Technical drawings
- Computers
- Economic factors (costs and prices)
2. Stages of Technological Projects
A technological project follows these stages:
- Needs – Identify a problem or need.
- Ideas
C Programming: Arrays, Functions, and String Handling
One-Dimensional Arrays
A one-dimensional array is a linear collection of elements of the same data type, stored in contiguous memory locations.
1. Declaration
Declaring an array tells the compiler its name, data type, and size.
data_type array_name[size];- Example:
int scores[5];// Declares an array named scores that can hold 5 integers.
2. Initialization
You can initialize an array at the time of declaration or assign values later.
| Method | Example | Description |
|---|---|---|
| Declaration with Size | int marks[3] = {90, 85, 95} |
Java Programming: Exceptions, Threads, and Networking
Java Exceptions: Checked vs Unchecked
Differentiating Exception Types in Java
Exceptions in Java are runtime errors that disrupt the normal flow of a program. They are classified into checked and unchecked exceptions.
Checked Exceptions are verified at compile time. The programmer must either handle them using try-catch blocks or declare them using the throws keyword. These exceptions usually occur due to external factors such as file handling, database access, or network issues. Examples include IOException,

Birth of the Organization
This stage marks the founding of an organization and represents a particularly risky phase in the organizational life cycle due to a high probability of failure. The failure rate is high because of the liability of newness, meaning the risks that come from operating in unfamiliar environments, often as first movers.
A new organization is fragile because it lacks a formal structure that provides stability and predictability in its processes and value-creating activities. The
