Electricity

We use electricity everywhere. 

When it gets dark, you turn the lights on, which run on electricity. You make your food in your microwave oven, which runs on electricity. You watch your favourite shows on your television, which runs on electricity as well.

In fact, the very device you are using right now to read this blog requires electricity to function.


Electricity is one of the most important inventions, and is very essential in today's world.


BUT WHAT IS ELECTRICITY?

Electricity is the set of physical phenomena related to the motion of matter that has a property of electric charge. 

For example, when electrons flow in a circuit, they produce electricity/electric current.


TYPES OF ELECTRICITY

There are two types of electricity:

• Static electricity:  It occurs when there is an imbalance between negative and positive charges in an object. This can be done by rubbing materials together which leads to the transfer of negative charge(electrons). 
For example, when you rub a balloon on your head for a while, your hair gets attracted by the balloon and points in the direction of the balloon.

• Current electricity: It is defined as the flow of electrons through a circuit/conductor. Conventionally, the current in the circuit moves away from the positive terminal and toward the negative terminal of the battery, but electrons move through the wires in the opposite direction. (Away from the negative terminal and toward the positive terminal of the battery).


CONDUCTORS AND INSULATORS

• Conductors: Materials which allow electric current to pass through them easily are called conductors. These are used when we want to help in the passage of electric current.
For example, silver and copper allow current to pass through them easily. Wires are made with conductors.

• Insulators: These are the opposite of conductors. Materials which do not allow electric current to pass through them easily are called insulators . These are used when we want to prevent the passage of electric current.
For example, rubber and glass do not allow electric current to pass through them easily.

So that was a brief explanation on electricity. I hope you learned something new by reading this blog.

Thank you for reading!

Special Relativity Explained

Hello everyone! Have you ever heard about Special relativity?Its a remarkable theory published by the well known physicist Albert Einstein.I am sure you must have heard of him. Now lets know a bit more about special relativity. Special Relativity is the  accepted and  well-confirmed physical theory regarding the relationship between space and time or space-time. In Albert Einstein's original pedagogical treatment, it is based on two postulates.They are: 1.the laws of physics are invariant in all inertial systems / non-accelerating frames of reference. 2.the speed of light in a vacuum is the same for everyone, regardless of the motion of the source of the light. Special relativity is the most accurate model of motion at any speed when gravitational effects are negligible. But still, the Newtonian mechanics model is valid as a simple and high accuracy approximation at low velocities relative to the speed of light(c). Special relativity implie...

Speed, Distance and Time | How are they related?

Speed, distance and time are very essential concepts when one starts to learn about physics. Talking about one of them naturally brings up the other two as well, since they are linked with each other. Let's find out how, and learn about them!  SPEED Speed is a measure of how fast something is moving. It is how quickly an object is changing it's position, and so, it is a scalar quantity .  • The speed of an object is said to be more when it is travelling faster and covers more distance in a certain time. • The speed of the object is said to be less when it is travelling slower and covers lesser distance in the same time. SI unit of speed : • m/s (metres  per second) • Commonly used : Km/h (Kilometres per hour) • m/h (miles per hour) How to calculate speed : speed = distance/ time DISTANCE The distance between two objects is a measure how far away the objects are from each other. It is the physical length between two objects. • The distance between two objects is...

General Relativity Explained

Have you ever heard about General relativity?  General relativity is a remarkable theory published by the well known physicist Albert Einstein. Let us know more about general relativity. General relativity is the geometric theory of gravitation published by Albert Einstein. Albert Einstein published this theory in 1915. It is the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton's law of universal gravitation , and gives a unified description of gravity as a geometric property of space and time, or space-time . THE CURVATURE OF SPACE-TIME AND THE EINSTEIN FIELD EQUATIONS The  curvature of space-time is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations. That is a system of partial differential equations. The Einstein field equations comprise a set of 10 equations in Albert Einstein's general theory of ...
