New Technologies and Their Origin Different technologies that answer our greatest dilemmas have begun to emerge throughout human history. From the camera to NASA’s telescopes are examples of the development of technology using physics. Great inventions have been born out of the curiosity of people seeking to know more and solve great dilemmas. From science […]

This topic Physics, Technology and Society deals with the correlation of these three since they are interconnected. Physics, technology and society give rise to one another in various ways. Some concepts of physics are used to develop technology which hence affect society. A country’s growth, both in the field of technology and in the education

A galvanometer is an electrical device used to measure the small value of currents. The galvanometer has gone through numerous versions since its invention in the 1800s. Mirror galvanometers, Tangent galvanometers, and Astatic galvanometers are some types of galvanometers being used currently. But the moving coil galvanometer is more commonly used than all other galvanometers.

The communication system of today is a complicated system composed of multiple components that must all operate in concert in order to function properly around the clock. The MODEM, on the other hand, is one of the most important and fundamental components of the communication system. This is an abbreviation for the terms modulator and

Potentiometer A potentiometer is an instrument used to measure the internal resistance of a cell by balancing it against the potential difference produced by passing a known current through a known variable resistance. The potential meter is an adjustable voltage divider formed by a three-terminal resistor with sliding or rotating contact. To change the potential

A cyclotron is a mechanical device invented by the American nuclear scientist Ernest O. Lawrence in the year 1929-1930 to accelerate the charged particle. Initially, it was made in small size with a limit to speed up the particles or ions at low volts of energy. The cyclotron, which was made earlier, had many limitations

A galvanometer has a wide range of applications as well as use. But what is a galvanometer? A device used to detect a small electric current and its magnitude is a galvanometer. The intensity of the current is indicated by the movement of the magnetic needle, which forms an important part of any galvanometer.  There

As the name suggests, the particle accelerator is an acceleration machine that can be used to provide very high speed and energies to the charged particles to save them in well-defined beams. These accelerators are mainly used for research in the field of particle physics. A cyclotron is also a type of cyclotron that provides

A transformer is an electrical device that transfers energy from one circuit to another by the mechanism of electromagnetic induction. In most cases, energy transmission necessitates a change in voltage and current. Transformers are used to raise or reduce the voltage of alternating current. Transformers are widely used. Some transformers are many floors high, such

An ammeter is a device that measures or notes the magnitude of current that passes through an electronic device or appliance. The ammeter is connected with the circuit for determining the value or extent of current that flows through a device. This is one of the functions of the ammeter. An ammeter is also known
