Electricity is one of the most important commodities in modern societies. This wonderful form of energy has thousands of uses and we are all surrounded by its various applications all across ourselves. But the question is how does the energy get converted into electricity that we all are able to use. Or how does electricity power up big cities? 

The fact is that we have become so accustomed to utilizing electricity that we cannot imagine a world without it. That is why it is essential to study electricity in its entirety. Even though the students start to understand the basics of electricity in the 8 or 9th standard. It is in the 10th standard that the real study begins. 

With this article, you will be able to understand everything that you will read in your class 10 physics and more importantly what comes within the purview of electricity. 

Types of Electric Components and how to develop physics notes:

We are going to begin by understanding the electric circuits. What are electric circuits?

Well, as per the CBSE, the closed path of an electric current is referred to as an electric circuit. This means that when the electric current passing is flowing in a set path without any breaks, an electric circuit is formed. 

You will also know about different symbols and markers that are often used in an electric circuit. Some of these are named as Lamp, Voltmeter, Resistor, Ammeter, LED, and many others. Down below, these components of an electric circuit are explained in brief:

Switch: It helps in turning the circuit on and off. 

Fixed Resistor: A resistor helps in restricting the electric current flow. A resistor that is fixed has the same resistance that can not be changed. 

Variable Resistor: This resistor limits the electric flow but its resistance limit can be managed. This component is useful in controlling the volume in a speaker or in variable lights. 

Lamp: When the current flows through the circuit, the lamp or the bulb gets turned on. 

Thermistor: This component helps in controlling the resistance of a circuit in relation to the temperature. During lower temperatures, the resistance increases and during higher temperatures, the resistance decreases.  

Light-dependent resistor (LDR): This component is used in the sensors of automatic lights and cameras. When the light level is lower, LDR has high resistance and when the light level is higher, LDR has lower resistance.   

Semiconductor diode: It helps the electric current to flow in one direction and be stagnant in the same direction. 

Check the following topics that are covered in class 10 physics.

What is a Potential Difference in Basic Physics?

A potential difference in simple terminology means the amount of energy transferred between 2 points on a circuit. A voltmeter can be added to the circuit in parallel to find out the potential difference. The notation for measuring the potential difference is V=E/Q where V is the potential difference, E is energy, and Q is charge. 

Types of Electric Current and Electric Circuits

Mainly, there are two kinds of electric current, alternating and direct. In direct current, the electrons flow in the same direction while in the alternating current, the electrons keep changing their direction. 

There are mainly two kinds of electric circuits, Series and Parallel. 

Series Circuits

Circuits that have all the electrical components connected in a single loop are known as the series circuits. In it, when the current starts to flow, it will pass through every component connected in the circuit and complete its cycle. In case any component is faulty, the circuit will breakdown and the current will not flow ahead. 

Parallel Circuits

In the case of a parallel circuit, the circuit is made in a way that different loops are created and the electrical components are joined at different places or loops. When the current starts to flow it gets divided between the components at different places on the loops. Parallel circuits are generally used in our homes for the purpose of electricity. 

Heating Effect of Electric Current

The basic physics covers the topic of what effects does heat has on the electric current. When the charge in a circuit gets induced and electrons start to flow, heat is generated. You must have noticed this with respect to the daily items in your life. If you use a phone for a long time, then it starts heating up. Same is the case with a fan, you keep it running for a while and it starts producing heat after a while. That is why you might have seen laptops always have a fan in them to dissipate heat. 

Metals are not able to accumulate heat in them and help to flow the electrons, that is why they are used in the wiring of the houses. The application of heating can also be seen in geysers, heaters, etc. 

These principles of physics are helpful in understanding the practical use of electricity in our daily lives. 

Electric Power

The rate at which the electrical energy is released or consumed in an electrical circuit is usually known as the power. The SI unit of power is Watt. When some amount of power is generated in a specific amount of time, electric power is generated. The scientific equation for this process is P = VI. 

Static form of Electricity

When two charged particles are rubbed together, there is an initiation of electrical current and you may witness some sparks. Atoms are present in every physical material and they have three types of particles in them. Protons that are positively charged, Electrons that are negatively charged, and Neurons that are neutral.

Using static electricity, certain charged objects can affect the other particles that are charged. The atomic structures of different particle models are also in the syllabus of class 10 science.

Friction

Friction is generated when materials that are insulated are rubbed against each other. In simple terms, when an opposite force acts on a force that is linear and decreases its motion, it can be termed as friction. To learn more about forces, you can click the given link. 

Electric Fields

Every particle that is charged carries some electric field around them. If two charged particles are much closer to each other, they will generate a high electric field. 

How to Learn Physics?

For a student of class 10 physics, the best way to learn and understand physics is by applying all the concepts in their own life. The reason why students show a keen interest in physics is because it can be applied to daily life. Physics has so many practical applications that one can co-relate with each of its topic in so many different ways. In class 10, it is just the introductory physics, and as we go forward to higher classes or choose physics as a subject in college, then you get to learn many interesting and detailed topics. Some of the topics are Electricity and magnetism, Thermodynamics, Quantum mechanics, Kinematics, Electromagnetism, Angular momentum, Newtonian mechanics, Gravitation, etc. Learn about the 

These concepts come in physics class 12 chapters and become easy to understand if we know the basics of physics concepts. There are some of the tips for learning physics for the students from which help can be taken.  

To learn the basic physics concepts, one should first thoroughly go through the textbook provided to them by their school. You should cover all the topics by understanding each one of them. Once done then sample papers of the physics should be solved to understand the concepts better.
