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 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 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[…]
Nuclear Fusion Nuclear energy is the energy in the core of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bond that hold atoms together. Nuclear energy can be used to makes electricity. But first the energy must be released. It can be released Read more about Nuclear Fusion[…]
Nuclear Fission Nuclear Energy is the energy in the core of an atom. Where an atom is a tiny particle that constitutes every matter in the universe. Nuclear Energy is discharged by nuclear reactions either by fission or fusion. In nuclear fusion, atoms combine together to form a larger atom. In nuclear fission, the division Read more about Nuclear Fission[…]
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[…]
Rigid body A rigid body is an extended area of material that includes all the points inside it, and which moves so that the distances and angles between all its points remain constant. Rigid body is an idealization of a solid body where the deformations occurring on the body are neglected. In other words, the distance between Read more about Rigid body[…]
Acceleration Whenever we are getting late for office and your driver is driving you to office, you ask your driver to hurry up and in response to that, you feel the car going faster. This is called acceleration. So, what is acceleration? Acceleration is a vector quantity that is defined as the rate at which Read more about Acceleration[…]
Displacement and Distance In Physics, we have to be able to find the motion or movement of the object. Where Object might be small or big. One of the important way to describe the motion of an object is HOW FAR THE ONJECT MOVED? This can be described by either of these two: Distance and Read more about Displacement and Distance[…]
Characteristics of Half Wave Rectifier A rectifier is a circuit which converts the Alternating Current (AC) input power into a Direct Current (DC) output power. A half-wave rectifier is a circuit that allows only one half-cycle of the AC voltage waveform to be applied to the load, resulting in one non-alternating polarity across it. Characteristics of Half Wave Rectifier: 1. Ripple factor: It Read more about Characteristics of Half Wave Rectifier[…]
