Electrical Power Transmission

I am here, the MyBook Guru. Dear, in transmitting power, effort must be ensure that power lost is reduced significantly. This can be easily achieved by following these steps,

Electromagnets

Hello! Let get started. Electromagnets are devices made of soft iron that behaves as magnet only when current is flowing through them. They lose all their magnetic properties when current stop flowing through them.

Electric Cells

Dear, it is my joyful duty to be elaborate on the topic - electric cells. As you know that the MyBook Guru is here, let get started. In the middle of 18th century, a man known as Volta placed a cloth soaked with brine solution in the middle of the copper rod and the zinc rod. He realized that current was flowing through the arrangement.

Must Read: Light Wave

Light! Everybody knows what light means, but there are things about light that seem unknown to us. Light is a visible ray radiated from a source. The source may be sun, moon, star, torchlight, lamp etc.

Fluids at Rest and in Motion

 Surface tension

I used to wonder why the water drops on leaves seem spherical. Later, I realized that it was due to the influence of surface tension. Surface tension arises due to the strong intermolecular forces that holds the liquid surface together.
