What electrical devices was created in 1960's?
Some electrical devices that were created in the 1960s were the slim angle TV which featured a five inch speaker and 23 inch screen. The belt massager was an exercise machine made in the 1960s. A bed wetting alarm called Lite Alert Wee Alert was also created in the 1960s.
Where are electronic devices made?
most are made in japan or china. but there are made all over the world
What are homes in Argentina made of?
concrete and wood concrete is commonly used and bricks are not commonly used.
What is the differences between electronic and mechanical devices?
Electronics Devices are those devices which are made from semiconductors like transistors fet mosfet amplifiers and ic's and other p-n junction devices. while mechanical devices are those devices which follow the mechanical principle such as strain gauge , machines and robot etc.
What is difference between good and bad conductors?
Good Conductors, such as silver, copper or aluminium, allow electric current to flow along them, while bad conductors (also termed "good insulators!) such as glass or mica or air impede or prevent electric current flow.Physically a good conductor is a material containing movable negative electric charges which are electrons or ositive electric charges termed holes. or in the form of ions, such as in the electrolyte of a battery. A proper design of a good electrical conductor takes into account the temperature that the conductor is able to endure without damage, as well as the quantity of current or electrical conductivity.Most familiar and affordable conductors are metallic because metals are elements or substances having one, two or three electrons in their valence shells and their atoms are arranged in a pattern of regular lattice structure called metallic bonding. The valence electrons are therefore free to move around the lattice of positively charged ions as a "sea of electrons".A bad conductor or good insulator is composed of a material which lacks mobile charges. Hence it resists flow of electric current because its internal electrical charges do not flow freely. Rgat is because its "valence" band containing the highest energy electrons is full, and so a large energy gap separates this band from the next band above it. Such good insulators are thereby made use of in electrical and electronic circuitry specifically to separate electrical conductors without allowing current to pass through themselves.But good insulators are also made use of as the dielectric of a capacitor that is capacitor consists of two good conductors called its plates separated by a non-conductive region comprising a bad conductor or insulator. Capacitors are extremely commonly used in electronic circuitry such as radio or television receivers. The bad conductor area of a capacitor is known as its dielectricwhich may be air or some material like mica. glass or ceramic. Above a particular electric field, known as the dielectric strength Eds, the dielectric in a capacitor becomes conductive. The voltage at which this occurs is called the capacitors' breakdown voltage that is basically the voltage above which the bad conductor can no longer stop direct current passing through it.
What are some examples where electrical conductors are used for?
Electrical conductors are used in wiring. They allow electricity to flow through the wire and into the item needing the electrical power. Wires are usually made of copper or aluminum because these metals are good electrical conductors.
Are toothpicks good electrical conductors?
no, because they are made out of wood, which i not a conductor...
Why are electrical and electronic appliances made of both conductors and non-conductors?
It obviously uses conductors to carry electricity through the system however non-conductive material is used for the reason of safety, organization of electrical components, and mechanical work.
What does an electrical insulator have?
Electrical insulators are made from materials that are poor conductors of electricity. Metallic elements are good conductors, non metallic elements are poor conductors. Some materials used as insulators are, paper, glass, ceramics, rubber and plastics.
What are electrodes made of?
It varies. Electrodes can be made of iron, carbon, platinum or any number of electrical conductors.
Is coins conductor or insulator?
Coins are made of metal and therefore they are good electrical conductors.
Why are electric wires don-not made of rubber?
Obviously, rubbers are not conductors. Wires are commonly made of copper.
Why semi conductors are preferrd over conductors?
Conductors transport electrical energy easily. You can transfer the energy at the electrical pole to you light bulb without much loss from friction through a conductor like copper. Some semi-conductors are very interesting because they can be made to vary the flow of electricity through them. A small electrical signal can control the resistance of electricity through the semi-conductor. Thus a small signal can be made into a large signal, this is called amplification.
Is a magnet an isulator?
That might depend on what material the magnet is made from, but usually magnets are made from metals or alloys, i.e., electrical conductors.
What is made out of copper?
Copper is an element made up of copper atoms. so there is no such thing as what it is made up of it is just atoms
What electrical devices have been made since year 2000?
I invented the i pod in the 20th to entertain the people of america and to show how music devices progresses faster then most devices made.
What are some electrical conductors and insulators of the household?
mostly anything made of metal is a conductor. Water is one of the only conductors that isn't. Any plastic, paper or glass is generally an insulator.
