Data structure is a way of organizing and storing data in a computer so that it can be accessed and modified efficiently.

• Data structures include arrays, linked lists, stacks, queues, trees, graphs, etc.

• They are essential for efficient algorithms and problem-solving.

• Example: An array is a data structure that stores a collection of elements in contiguous memory locations.

An array is a data structure that stores a collection of elements of the same type. There are different types of arrays like one-dimensional, two-dimensional, and multi-dimensional arrays.

• One-dimensional array: Stores elements in a single row or column.

• Two-dimensional array: Stores elements in rows and columns.

• Multi-dimensional array: Stores elements in more than two dimensions.

• Example: ['apple', 'banana', 'orange']

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law formula: V = I * R (Voltage = Current * Resistance)

• Example: If a circuit has a voltage of 12V and a resistance of 4 ohms, the current flowing through it would be 3A (12V = 3A * 4 ohms)

• Ohm's law helps in calculating the relationship betwe...read more
