Encapsulation is the process of hiding implementation details and exposing only necessary information.
Encapsulation helps in achieving data abstraction and security
A real-time example of encapsulation is a capsule or a tablet, where the medicine is encapsulated and the user only knows the dosage and the effects of the medicine, not the actual ingredients or the manufacturing process
Another example is a car, where the u...

Swapping two numbers without using a temp variable
Use arithmetic operations to swap the values
Add the two numbers and store the result in the first variable
Subtract the second variable from the result and store it in the second variable
Subtract the second variable from the first variable to get the original value of the second variable
Example: a=5, b=7; a=a+b=12, b=a-b=5, a=a-b=7

The current in a transformer is made by inducing voltage across the primary coil.
The primary coil of a transformer is connected to an alternating current (AC) source.
The alternating current in the primary coil creates a changing magnetic field.
This changing magnetic field induces a voltage across the secondary coil.
The induced voltage in the secondary coil causes a current to flow through it.
The current in the secondar...
DC shunt motors are a type of direct current motor that have a parallel field winding and a series armature winding.
DC shunt motors have a parallel field winding and a series armature winding.
They are commonly used in applications that require constant speed and moderate starting torque.
The speed of a DC shunt motor can be controlled by varying the field current or the armature voltage.
DC shunt motors are widely used i...
A DC shunt motor is a type of direct current motor that has a shunt field winding connected in parallel with the armature winding.
The field winding and armature winding are connected in parallel
The shunt motor has a relatively constant speed-torque characteristic
The speed of the motor can be controlled by varying the field current
The motor provides good starting torque
The shunt motor is commonly used in applications wh...
