Facts about Modern Science

Facts that prove science and technology change the world. We all know in today's world technology involved so fast and change the society or living standard of common man life. In the last 100 years we see some drastic changes in human civilization here we see some important invitations from modern days.

Facts about electricity

Facts about electricity

Electricity is one of the useful invitations in modern days. Benjamin Franklin was the first person who discovered electricity in 1752 by using a kite and key on a rainy day when the thunderstorm when the storm clouds transferred to the kite and electricity flowed down the string and gave him a shock. he explained the element of current flow in two charges one is positive other is negative.

Alessandro Volta physicist who invented the first electric battery in the year 1800 volta use a voltaic pile. The pile was made up of zinc and copper plates with vinegar- or brine-dampened pieces of leather or pasteboard placed in between each plate. The plates were then stacked in alternating order one on top of the other with the bottom plate and the top plate acting as the positive and negative terminals.

Morden used of battery

Nowadays the batteries are more powerful and lightweight and use several things like remote controls, torch, wall clock, flashlight, hearing aids, weight scales, etc. Rechargeable batteries are also used in various devices like digital cameras, mobile phones, batteries of vehicles, video game devices, remote control cars, home maintenance tools, and many more. The unit volt is used to measure the force of an electric current. This unit is used in modern-day battery

Electric Motor invention

 

The first electric motor was an invention by Thomas Davenport. The first official battery-powered electric motor was in 1834. Early Motion devices using electromagnetic fields were created by Joseph Henry and Michael Faraday but at that time this could help humankind but be important for leading the way to better motors in the future. On the other side, Davenport motors were able to run a model trolley on a circular track and do other tasks. The trolley later turned out to be the first important application of electric power. after 1835 the first light bulb was an invention by Thomas Edison. Electric motors may be classified by considerations such as power source type, internal construction, application, and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless.

Modern Electric Motor Used

Electric motors

Today Electric Motors are used in a wide range of applications, such as fans, power tools, appliances, electric vehicles, and hybrid cars. elevators. 

The most and hybrid model used in Electric Cars. Elon musk company tesla is one of the world's most valuable electric automaker companies the net value of this company is over 1 trillion. The Advantage of Electric vehicles are less air pollution and noise pollution emission-free It is also cheap to refill, you could either charge it at any local charging station free of charge or at home by the household charging station which is installed in your garage. 

Modern renewable sources of Energy

Charles Fritts created the first commercial solar panel. nowadays solar panels are so common in every household this is one of the most popular renewable energy sources currently. We can create our own energy from renewable energy where it will be used. This could be installing PV solar cells on the roof of your home, in a developer or administrator, office, or school building.

Renewable sources are good for our environment. most of the sources are used for natural Renewable Resources. Solar Energy, Bio-fuels, Hydrogen, Hydropower, Tidal Energy, Ocean Thermal Energy, Wind Energy, Geothermal Energy, etc.
