Lightning Safety (Indoor)


“Houses and buildings have an abundance of grounding paths makes them generally safe lightning shelters, but to ensure maximum safety during a storm: 1) Don’t use any wired appliance or device. Wireless appliances (cordless phones, razors, etc) are safe to

Transfer of Charge


“A electroscope consists of a glass jar in which two strips of gold leaf are suspended from a metal rod that conducts electricity. The rod, which enters the jar through a stopper made of a material that does not conduct

Types of Charges and Their Interaction


“All objects surrounding us contain large amounts of electric charge. There are two types of electric charge: positive charge and negative charge. If the same amounts of negative and positive charge are found in an object, there is no net

Charging by Friction


“If two objects are rubbed together, especially if the objects are insulators and surrounding air is dry, the objects acquire equal and opposite charges and an attractive force develops between them. The object that loses electrons becomes positively charged, and

Electric spark


“An electric spark is a type of electrostatic discharge that occurs when an electric field creates an ionized electrically conductive channel in air producing a brief emission of light and sound. A spark is formed when the electric field strength



“Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of frozen raindrops bump into

Use of electroplating


“Use of electroplating are as follows: Electroplating is used in many industries for functional and decorative purposes. Some well-known examples are chrome-plating of steel parts on automobiles. Steel bumpers become more corrosion-resistant when they have been electroplated with first nickel

Process of electroplating


“The cations associate with the anions in the solution. These cations are reduced at the cathode to deposit in the metallic, zero valence state. In the process of electroplating, metal salt solution is taken in a container. Salt of metal



Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating.

Light Emitting Diodes (LED)


“A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. An LED consists
