Frequently Asked Questions on Electric Potential Energy       What is electric potential energy? Electric potential energy or electrostatic potential energy is the amount of work done against electrostatic force of interaction. Electrostatic field is a conservative force field and it obeys inverse square law. When a charged particle (q) is displaced from a […]

Introduction: V-l characteristics of Ohmic carry an important weightage in the IIT-JEE exams. Hence, it is important to have the best handy study material that will help the students clear their concepts on this topic. To make your preparations more productive, you can opt for Unacademy’s live classes and batch courses that are a great

What is electric potential?  No charge can exist individually, and hence every conductor or material experiences a system of charges. Electric charge and its associated concepts are always viewed in a set of charges. Thus, electric energy or electric potential energy is defined as the work done by a charge to change its position in

Introduction to Semiconductor Diode Semiconductors are critical components of contemporary electronic gadgets, serving as the building blocks of these devices. They can act both as insulators and as conductors. Semiconductors are crucial to the effectiveness of electronic devices. Their adaptability allows for developing a wide range of electronic devices to meet a wide range of

Equipotential Surface For a given charge distribution, the locus of all the points having the same potential is called Equipotential Surface. Equipotential surface, as the name defines, is a surface on which potential is equal everywhere. It means that if we draw a surface in such a way that the electric potential is the same

Have you noticed how many insulation products are made of plastic, wood, or even glass? What is the reason for this scenario? Why aren’t we getting electric shocks when using plastic or wood? What is the reason that metal wires can only generate severe shocks? This chapter will look at dielectrics, the Polarisation of the

Polarisability is the ability of a molecule to attain an electric dipole moment when an external field is applied to it. The applied electric field can distort the molecule. A dipole moment is induced into a molecule when an external electric field is applied, as this field interacts with the molecule’s electron cloud and can

What is a nickel-metal hydride cell? Before we get to that, “What is a cell?” A cell is a  source of energy that converts chemical energy into electrical energy. There are two types of cells—primary (non-rechargeable) cells and secondary (rechargeable) cells.  A Nickel-metal hydride cell is a rechargeable cell. It uses a compound of Nickel

What stream to choose after 10th? In a three-phase system, the line voltage is the potential difference between any two lines or phrases. The potential difference between any two phases is referred to as the phase voltage. The three-phase domestic power supply or 440 volts, is referred to as the line voltage. The potential difference

The electrostatic or electric potential is defined as the total work done by an electric charge to move from one position to another in the given electric field. The electric potential is a scalar quantity. In the following article, we will understand the basic concept of electricity and electric charge. We will further establish why
