Electronics Engineering

Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

Men wearing flip flops?

Men can wear flip flops but usually don't wear them as much as women do as representing and making one sexy is not considered a part of the genderType your answer here...

Can a capacitor be used to help smooth out inverter surges?

A: YES it can to a point but as speed of surges increases the capacitor will start to behave like a coil

How do you figure the watts of a 110 volt pump that is 135 hp and has an amp draw of 54?

Yes, power = voltage x current = 54 x 110 = 5940 watts. But the odd thing is the rated horsepower. I was taught that one horsepower = 746 watts, so 135 hp = 100,000 watts. Are you certain that the pump is rated at 136 horsepower? Or can anyone else address the discrepency? W=volts X amps; therefore W= (110)(54)

What happens when clipping occurs in a inverting amplifier?

The output waveform will be limited to the difference between the supply and ground (or between the positive and negative supplies).

This causes distortion of the output waveform.

Why metals conduct electricity?

Metals undergo a metallic bonding, meaning when two metals shares their valence electron they undergo metallic bonding. Within the metallic bond, there are enormous amount of free electrons or what we call " SEA OF ELECTRONS, MOBILISE NOT STATIONARY"constantly moving within the lattice. As we know electrons can carry electric and thermal energy through vibrations and pass the energy from each other throughout the lattice or structure. if u put a piece of metal under the sun light, eventually it will get hot and that's because electrons absorb the thermal energy from sun light and gets excited, the same way " when a guy see a hot girls" and starts vibrating.

What do telecommunication engineers do on a typical working day?

Telecommunication Engineers are concerned with establishing communication by means of telephones, telegraphs, radar, radio, radio navigational aids, TV, and teleprinters. Important towns, cities, trade centers, harbors and ports are connected with underground cables or radio links. Countries and continents are brought closer by means of fast-emanating, information-carrying communication networks. All this has been made possible by the telecommunication engineer. Telecommunication engineers deal with line and wireless communication, or radio communication. Line communication is handled by telephone/telegraph engineers. The work comprises the installation, supervision, and maintenance of telephone exchanges and telephone lines. The radio communication engineer's work is concerned with the designing, installation, maintenance and periodical testing of broadcasting and telecasting systems and studios, and transmitting and receiving stations.

Why is a short circuit bad?

If you have a circuit, the electrons will move through it and reach the negative terminal of, let's say, a battery. But if you have a direct line from the anode to the cathode, the electrons will ignore everything else, such as any LED's or motors you have on the circuit. In the case of electrical outlets, the cathode is unable to withstand as much electricity as the anode gives out. Also, this can cause an "arc" of ionized plasma to jump from the anode to the cathode, and I don't think you want to arc weld your electronics to the outlet...

Why the received signal in analog communication is distorted by the channel noise than that of digital communication?

If an RF signal is AM modulated with a analogue signal any noise will add or subtract to the amplitude of the RF signal and will be present in the audio signal after detection, also will the noise add itself to the audio signal, where as in digital communication a slight variation in the amplitude of the signal is of no concern because you only work with ones and zeros, it's high or it's low

What are two other names for the system bus?

System bus, memory bus, front side bus (FSB), host bus, local bus, or external bus.

What happens to an inductive circuit when capacitance is added for power factor correction?

The capacitance counter acts the inductivity (decreases it) without impacting the resistivivity, thus increasing the power factor, or resistivity / inductivity ratio.

Who or what was the electrical term 'farad' named after?

The electrical term "Farad" was named after the popular scientist Michael Faraday. Faraday is well known for his work in electrical components and electro-magnetism. His most famous invention is called the Faraday Cage.

Why 11.0592 MHZ frequency is used with at89c51?

It gives the possibility to generate several precise baudrates for serial communications. With 12 MHz you introduce small errors that will however be acceptable for hobbyists.

Why the entire frequency range of 20hz-20khz is not used in telephony?

Because it is not necessary, and providing that bandwidth would increase cost and complexity. While the full range of 20Hz-20KHz is required for proper rendering of music, telephony, by standard, only requires a 3.5KHz bandwidth. You can hear and understand the spoken voice with only this range. You do not need the extended musical range.
