Velocity

Velocity What is Velocity? Velocity is the Rate of change of position. I.e. Rate of displacement with time is called velocity. A velocity of an object is the rate of change of the object’s position with respect to a frame of reference and time, it might sound complicated but velocity is basically speed in a Read more about Velocity[…]

Photodiode Symbol

Photodiode

Photodiode A Photodiode is a p – n junction diode that can absorb photons and generate either a Photo Voltage or Free Carriers that can produce Photocurrent. They are used for detection of Optical signals and for conversion of Optical Power to Electrical Power. A Photodiode is an example of an optoelectronic junction device, which Read more about Photodiode[…]

Nuclear force

Nuclear Force

Nuclear Force Nuclear force is one of the four fundamental forces of nature, the others being gravitational and electromagnetic forces. In fact, being 10 million times stronger than the chemical binding forces, they are also known as the strong forces. The nuclear force acts between all of the particles in the nucleus, i.e., between two neutrons, Read more about Nuclear Force[…]

Light Emitting Diode (LED)

Light Emitting Diode (LED)

Light Emitting Diode (LED) A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength. The output from an LED can range from red to blue-violet. Some LEDs emit infrared (IR) energy, such a Read more about Light Emitting Diode (LED)[…]

Capacitance

Capacitance When a positive charge q is placed on a conductor that is insulated from ground, an electric field emanates from the conductor to ground and the conductor will have a nonzero potential V relative to grounds. If more charges is placed on the conductor, this voltage will increase proportionately. The ratio of charge to Read more about Capacitance[…]

Capacitor

Capacitor

Capacitor The capacitor is a component which has the capacity to store energy in the form of an electrical charge producing a potential difference across its plates, much like a small rechargeable battery. There are many different kinds of capacitors available from very small capacitor beads used in resonance circuits to large power factor correction Read more about Capacitor[…]

Momentum

Momentum According to Newton’s Law of Motion, all moving bodies continue to be in the state of rest or motion unless interfered by some external force. The mass principle can be applied to momentum i.e. if the mass and velocity of an object remains same then the momentum of the object remains constant. What is Read more about Momentum[…]
