Electric Field and the Movement of Charge

Perhaps one of the most useful yet taken-for-granted accomplishments of the recent centuries is the development of electric circuits. The flow of charge through wires allows us to cook our food, light our homes, air-condition our work and living space, entertain us with movies and music and even allows us to drive to work or school safely. In this unit of The Physics Classroom, we will explore the reasons for why charge flows through wires of electric circuits and the variables that affect the rate at which it flows. The means by which moving charge delivers electrical energy to appliances inorder to operate them will be discussed in detail. One of the fundamental principles that must be understood in order to grasp electric circuits pertains to the concept of how an electric field can influence charge within a circuit as it moves from one location to another. The concept of electric field was first introduced in the unit on Static Electricity. In that unit, electric force was describ…

Creating Awareness of Mosquito Bite

We all know about mosquito bites how danger they are in some cases.In some cases  it
may also leads to death of the person some cases like malaria,dengue,typhoid

Rather than spraying neighborhoods with pesticides ordousing ourselves with chemical repellentsto ward off mosquitoes, wouldn’t it be great if the insects simply didn’t like how humans tasted and left us alone?
That’s the concept behind some new research from scientists at Johns Hopkins University. They’re studying how the brains of mosquitoes process tastes and smells, in hopes of identifying a way to make “human flavor” distasteful to mosquitoes. Their work, published online in the journal Nature Communications, focuses on Anopheles gambiae, a type of mosquito that carries malaria, an illness that kills about 438,000 people around the world each year and sickens more than 200 million. The research not only suggests a possible path to a malaria-free future, but it hints at ways othermosquito-borne illnesses, like the Zika vi…
