## Chapter-1:Electric Field And Potential

### Introduction:

An electric field surrounds an electric charge, and exerts force on other charges in the field, attraction or repelling them. Electric field is sometimes abbreviated as E-field. The electric field is defined mathematically as a vector field that associates to each point in space the force per unit of charge exerted on an infinitesimal positive test charge at rest at that point.

### Chapter Analysis:

​A total of 20 questions have been asked from this chapter in the past 11 years, with the year 2014 alone handling 5 question. Last year was a hike in the number of questions asked with 3 question being asked. The number of questions in the other years have been limited to 2 at max. This chapter falls in the category of medium weighted chapter and we should not expect more than 2 questions from this chapter in the upcoming papers.
The below given graph will illustrate the above-mentioned analysis: Year 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009

5. Online video lectures must be looked upon as they will provide interactive animations thereby making the subject matter easier to understand.

## Chapter-2:Gauss's Law

### Introduction:

Gauss Law also known as Gauss’s Flux theorem is a law relating the distribution of electric charge to the resulting electric field. The surface under consideration may be closed one enclosing a volume such as a spherical surface. The law was first formulated by Joseph-Louis Lagrange, followed by Carl Fredrich Gauss in 1813.

### Chapter Analysis:

With only 3 question being asked in the past 11 years directly from this chapter, we can consider this to be one of the low weighted chapter. However, the concept of this chapter is used directly in various another chapter and hence must not be overlooked. The past 4 years have seen no question being asked from this chapter and hence we should not be expecting any question from this chapter in the near future.
The below given graph will illustrate the above-mentioned analysis: Year 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Questions 0 0 0 0 1 0 0 0 1 1 0

### Tips and Tricks:

2. Making Flash Cards and Flow Charts will help in quick revision
3. A List of important keywords with their meaning must be maintained
4. All the past year questions must be solved thoroughly

## Chapter-3:Capacitors

### Introduction:

A capacitor is a passive two-terminal electronic component that stores electrical energy in an electric field. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as Condenser or Condensator.

### Chapter Analysis:

With the exception of the year 2013, we see that 1 question has been asked from this chapter every year from 2009-2019. The pattern is astonishing, and we can expect 1 question from this low-weighted chapter in the coming years.
The below given graph will illustrate the above-mentioned analysis: Year 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Questions 1 1 1 1 1 1 0 1 1 1 1

The important topics to be covered from this chapter are:
• Conductors and Insulators
• Free Charges and Bound Charges inside a Conductor
• Dielectrics and Electric Polarization
• Capacitors and Capacitance
• Combination of Capacitors in Series and Parallel
• Capacitance of a Parallel Plate Capacitor with and without dielectric medium
• Energy Stored in a Capacitor

### Tips and Tricks:

• The students must begin with reading the NCERT portion as it has a good basic explanation of the chapter and helps form the base for further reading. Here is the link to the NCERT PDF version of the mentioned chapter:
• Flash Cards are to be created by the students so that they are able to revise the parts and their functions easily.
• Mnemonics may be created uniquely by the student so that they are able to retain the parts in their mind easily.
• All the past year questions must be solved so that one understands the type of questions that are asked in the paper.
• Revision every week should be done to keep the chapter fresh.

## Chapter-4:Current Electricity

### Introduction:

An electric current is the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric change through a region. In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionized gas.

### Chapter Analysis:

This happens to be one of the most important chapter from Physics in the NEET Syllabus. With 31 questions asked in the past 11 years, it is one of the most frequented chapter by the paper setters. The last 3 years had 8 questions being asked from this chapter. The number of questions peaked in 2009 when 5 questions were asked. Hence, we can expect atleast 3 questions from this chapter in the upcoming papers.
The below given graph will illustrate the above-mentioned analysis: Year 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Questions 3 3 2 1 3 3 2 2 3 4 5

The important topics to be covered from this chapter are:
• Electric Current
• Drift Velocity, Mobility, and their relation with Electric Current
• Ohm’s Law and Electrical Resistance
• V-I characteristics (Linear and Non-Linear)

4. All the past year questions must be solved thoroughly

## Chapter-5:Thermal And Chemical Effect Of Current

### Introduction:

Chemical Binding is due to electrical forces between electrons and nuclei, and between electrons. It should therefore be possible to convert differences in chemical binding to electrical energy. Conversely electrical energy can cause chemical changes. This large field is called electrochemistry and is properly studied as part of chemistry.

### Chapter Analysis:

Only 4 questions have been asked from this chapter in the past 11 years of NEET. The last 3 years have seen no question being asked and thus, this is a low weighted chapter. An all exclusive chapter, we should not be expecting more than 1 question from this chapter in the near examinations.
The below given graph will illustrate the above-mentioned analysis: Year 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
