Capacitance and capacitors

Non-polar molecules lack charge at the ends of the molecule. These molecules, instead, have electrons dispersed equally and are symmetrical all over. The electrons of the molecules cancel each other and are finely distributed.  Non-polar molecules do not have separate molecular charges and lack the positive and negative poles, unlike polar molecules. Non-polar molecules can […]

Have you ever wondered about what makes your watches work and show you time? What does the battery have that makes the watch work well and sound? If you look into the watches, the mercury cell keeps your watches and many more appliances on the go. These mercury cell applications have a prominent history in

We know about subatomic particles such as protons,electrons and neutrons.”Protons” Have +ve charge, electrons have -ve charge and neutrons have no charge, that is they are neutral.The total charge in a material is the number of charges multiplied by the charge of one electron. Electric charge is denoted by the letter ‘q’ or ‘Q’. So,

A Geiger counter (also known as a Geiger-Muller tube) is a device that detects and measures all forms of radiation, including alpha, beta, and gamma radiation. It is made up of a pair of electrodes that are surrounded by a gas. A strong voltage is applied across the electrodes. Helium or Argon are the most

In an electrical device, the I-V Characteristic Curves are an established collection of graphical curves that are used to define its operation inside an electrical circuit. I-V characteristic curves, as the name implies, depict the relationship between the current flowing through an electrical device and the voltage applied across its terminals. I-V characteristic curves are

Like a miniature rechargeable battery, a capacitor is a component that can store energy in an electrical charge. It produces a (static voltage) potential difference between its plates. Capacitors come in various shapes and sizes, ranging from bead-like capacitors used in resonance circuits to enormous power or energy factor correction capacitors. They all accomplish that

Ionic and covalent bonding are two extreme types of chemical bonds; however, practically all bonds are intermediate, which can be explained by polarising (or deforming) the shape of ions. Even though most metal–nonmetal pairings exhibit the features of ionic compounds, there are a few exceptions that occur when the anion’s outermost electrons are strongly attracted

Equivalent Conductance The conductance of a volume of solution containing one equivalent of an electrolyte is known as equivalent conductance. The symbol for equivalent conductance is Λ. Consider the volume of solution Vcm³ having one equivalent of an electrolyte. It has the same conductance as equivalent conductance, Λ. We also know that specific conductance, κ

A device which uses an electric charge to remove specific impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues is referred to as an electrostatic precipitator. Electrostatic precipitators, which were originally meant to recover valuable industrial-process materials, are now employed for air pollution control, particularly for eliminating dangerous particulate

Semiconductor devices are made up of semiconductor materials like germanium and silicon with semiconductor properties. For example, it partially allows electricity into it. These semiconductor devices have a wide range of applications in rectifications, ionisations, power devices, solid-state lasers, and optical sensors. Moreover, these devices are cheap, reliable, and compact. This article provides a detailed
