Tension

Tension The most important application of Newton’s motion Laws is the explanation of tension. Ropes and strings are very useful in machines and mechanical systems. These are used to push or pull heavy loads. We can see the tension in using of ropes or cables. If we consider a load which is pulled by a rope, a person is Read more about Tension[…]

NPN Transistor Construction

NPN – Transistor

NPN – Transistor A transistor is a semiconductor device which is used to switch or amplify electronic signals and electric power. It consists of semiconductor material mostly with at least three terminals for connection to an external circuit. In all the fields of electronics, transistors are used for almost all practical purposes. A semiconductor is mainly used to Read more about NPN – Transistor[…]

Heat

Heat

Heat Heat flows from the body at higher temperature to the one at lower temperature. The flow stops when the temperature will be equal and the two bodies are then in thermal equilibrium. Heat is energy that flows between a system and its environment by virtue of a temperature difference between them. Heat is a Read more about Heat[…]

Density

Density Density is a fundamental concept in physics, it is essentially, a measurement of how tightly matter is crammed together. The principle of density was discovered by the Greek Scientist Archimedes. What is Density? The density of a material shows the denseness of that material in a specific given are. This is taken as mass Read more about Density[…]

Electric Charge

Electric Charge

Electric Charge Electric charge is the property of sub-atomic particles particularly includes electrons and protons. Electrons have negative charge, protons have positive charge and neutrons do not have any charge. Or it is a physical property of matter which causes the force when places in any electromagnetic field. What is Electric Charge? Electric Charge is Read more about Electric Charge[…]
