Quartz watch movements are powered by a battery, while automated watch movements are powered by a complex system of gears, springs, and other mechanical components used to keep time. Read this article to find out more about Quartz and Automated Movement in Watches and how they are different from each other. What is Quartz Movement in Watches? Quartz-movement watches are powered by a battery-operated quartz crystal oscillator. It was first developed in 1960. Quartz watches are the most popular because of their accuracy and low cost. One of the main advantages of quartz-movement watches is their great accuracy. A ... Read More

mAh (milliampere-hours) refers to a battery's capacity, or the amount of energy it can store and deliver. NiMH (nickel-metal hydride) refers to the chemical composition of the battery. Read this article to find out more about NiMH and mAH batteries and how they are different from each other. What are NiMH Batteries? In NiMH batteries, hydrogen is used to store energy. Nickel Metal Hydride consists of a nickel hydroxide positive electrode plate, a hydrogen ion negative electrode plate, potassium hydroxide or another alkaline electrolyte, and a separator. NiMH batteries are commonly used in cell phones, digital cameras, pagers, electric toothbrushes, ... Read More

Electric Charge and Static Electricity

Introduction The movement of the charged particles is responsible for electric energy. Energy obtained from the kinetic energy or potential energy of the charged particles is the electric energy. Charged particles are atoms, molecules, or ions with a charge. The force of attraction or repulsion between the charged particles ends on coulomb’s law. Electricity is an important form of energy. When there is a disturbance in the attractive force between the charged particles the atom gains or loses electrons. These free electrons are responsible for electricity through them. Electricity is the movement of electric charges. What is a Static ... Read More

Introduction Most people are very doubtful about the terminology ‘Potential’. In our school time when we first time listened to this term, we learned that potential is somewhat related to the position. However, it means capacity or strength. The term electric potential represents the strength of electricity. When we start a study for electricity, the first thing we have to face is a charge. The charge is the base of electronics. It is of two types; positive and negative. As we proceed with the charge, we come to know about the electric field, electric potential, potential energy, dipole, etc. Every ... Read More

Introduction When we study a charge or a system of charge, we see that every charge has a definite amount of electric field which exerts the electrostatic force of repulsion or attraction on other charges and charged particles according to their nature. The effect of electricity can be experienced with the help of a unit charge, also known as a test charge. The electric field around a charge or system of charge can be described in two forms; The electric field and The electric potential. What is the Electric Potential of a Dipole and System of Charges? The electric potential ... Read More

Introduction Karl Friedrich Gauss is widely regarded as one of the greatest mathematicians of all time. Some consider him to be the greatest.Gauss discovered a way to think about Coulomb's law that allows us to calculate the electric field of charge distributions in a straightforward manner. Although Gauss did not discover a new physical law, his restatement of Coulomb's law was equally important. In this tutorial we will describe about electric flux, concept of eclectic flux, the flux of electric field, unit and dimensional formula of electric flux. To comprehend Gauss' law, we must first grasp the concept of ... Read More

Superposition Principle and Continuous Charge Distribution

Introduction Electric charges in the field of electricity and of magnetism, display the fundamental property of particles of matter. Both positive and negative charges exist together within a circuit and therefore display their different characters. For example, when the accumulation of one kind of charge exceeds then it results in positing the character of repealing, or when both the charges present in exceeding amount then they show the charges are attracted to each other. Electrons are known to be the negative charges and protons are known as positive charges. Electric Charge and its Properties Electric charge can be referred to ... Read More

Continuous Charge Distribution

Updated on 13-Oct-2022 11:19:47
Introduction: Charge Distribution Let us take a very light rod AB (as shown in the figure 1) of negligible mass and hang three mass ‘m’ each. So the total mass of the rod will be ‘3m’. But the mass of each part of the rod is not uniform, some parts will have more mass like CD and some parts like EF will have less mass. Images Coming soon Figure-1 This is because masses are concentrated only in some parts and this case is known as discrete mass distribution. Similarly, if we take a rod PQ (as shown in figure 2) ...
