How is Electrical Resistance Measured?

Electrical resistance is the resistance to the flow of electrical current. This theory was discovered by George Ohm in the 19th century. Resistance is measured in ohms. Electricity is nothing but electrons flowing. In an electrical current, the atoms in the material allow the flow of electrons. If there is poor conductivity it means that…

What are plastids?

Food is an important requirement not only for human beings but even for plants and animals. All living organisms require food to survive and therefore, storage of food is also very important. Plastids are special structures inside the plant cell that helps in storing food for the plants. Plastids are also found in different algae,…

What are chemical compounds?

We have all heard about different chemical compounds like baking soda, carbon dioxide and calcium chloride but do we really know what exactly these chemical compounds are. Chemical compounds are chemical substances, which are made up of two or more chemical elements. Since every chemical compound is made up of two or more chemical elements…

What are chemical reactions?

Are you interested in learning more about chemical substances and how they are made? If you are then you must definitely know more about chemical reactions because chemical reaction is a process where chemical substances transform from one substance to another. Chemical reaction is a process in which electrons are constantly breaking and forming to…

What are platelets?

Platelets are small red cells that are generally found in human and animal blood. Platelets are also known as thrombocytes, and they do not have a specific shape. If the count of platelets in your blood is too high then you might have problems like frequent blood cots that might lead to problems like heart…
