ELECTRO MAGNETIC INDUCTION

ELECTRO MAGNETIC INDUCTION

Summary:

Electromagnetic induction is that the method of generating current with a magnetic flux . It occurs whenever a magnetic flux and an electrical conductor, sort of a coil of wire, move relative to a minimum of each other . As long because the conductor may be a component of a loop , current will flow through it whenever it crosses lines of force within the magnetic flux .
The Current Produced by a Magnet
The device with the pointer in an ammeter. It measures this that flows through the wire. The faster the magnet or coil moves, the greater the number of current that's produced. If more turns were added to the coil or a stronger magnet were used, this is often ready to produce more current also .
The direction of this that's generated by a moving magnet are often understood as, If the magnet is moved back and forth repeatedly, this keeps changing direction. In other words, AC (AC) is produced. AC is electrical current that keeps reversing direction.
How Electromagnetic Induction is used
Two important devices depend on electromagnetic induction: electric generators and electric transformers. Both devices play critical roles in producing and regulating the electrical current we believe in our daily lives. Electric generators use electromagnetic induction to vary K.E. to electricity . They produce electricity in power plants. Electric transformers use electromagnetic induction to vary the voltage of electrical current. Some transformers increase voltage and other decrease voltage.

Electric generators and electric transformers use electromagnetic induction to urge electricity or change the voltage of electrical current.

ELECTRO STATICS

ELECTRO STATICS electro statics small summary of the topic Electrostatics, as the name implies, is the study of stationary electric charges. A rod of plastic rubbed with fur or a rod of glass rubbed with silk will attract small pieces of paper and is said to be electrically charged. The charge on plastic rubbed with fur is defined as negative, and the charge on glass rubbed with silk is defined as positive. Electric charge Electrically charged objects have several important characteristics: Like charges repel one another; that is, positive repels positive and negative repels negative. Unlike charges attract each another; that is, positive attracts negative. Charge is conserved. A neutral object has no net charge. If the plastic rod and fur are initially neutral, when the rod becomes charged by the fur, a negative charge is transferred from the fur to the rod. The net negative charge on the rod is equal to the net positive charge on the fur.

Semi conductor electronics

SEMI CONDUCTOR ELECTRONICS Brief summary: Semiconductor Basics If resistors are the most basic passive component in electrical or electronic circuits, then we have to consider the Signal Diode as being the most basic active component. However, unlike a resistor, a diode doesn't behave linearly with reference to the applied voltage because it has an exponential I-V relationship and thus can't be described simply by using Ohm’s law as we do for resistors. Diodes are basic unidirectional semiconductor devices that will only allow current to flow through them in one direction only, acting more like a one way electrical valve, (Forward Biased Condition). But, before we've a glance at how signal or power diodes work we first got to understand the semiconductors basic construction and concept. Diodes are made from a single piece of Semiconductor material which has a positive “P-region” at one end and a negative “N-region” at the other, and which has a resistivity value some

Optics

OPTICS Optics is one among the branches of physics which deals with Study of light It explains about the behavior and properties of light. Optics is subdivided into two branches. Ray Optics and wave Optics Because light has dual nature. Light can be considered as a ray or it can be considered as a wave. The study of Optics also includes the construction of some Optical instruments and it Describes the behavior of visible light , Ultraviolet , And infrared light. Because light is an electromagnetic wave. Other sorts of electromagnetic wave like x-rays microwaves and radio waves exhibit similar properties. The study of optical science Is relevant to Some of the other studies including astronomy, various engineering fields, Photography And Medicine field like Ophthalmology and optometry. Also Optics include some practical applications We found in variety of Technologies In our daily to day life Including mirrors, lenses, telescopes microscopes, lasers and fiber
