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.

The role of statistic in electrical engineering?

Over the past few years the EU has begun taking some steps against the spread of nuclear weapons within its Common Foreign and Security Policy (CFSP). At the Thessaloniki Summit June 2003, the European Council adopted its first draft Strategy against the proliferation of Weapons of Mass Destruction (WMD). In order to assess the significance of the Strategy, this paper will first present and evaluate the Union's record in the field, then review the newly released Strategy, and finally make suggestions as to how it can be improved. The EU is not an unitary actor in the nuclear non-proliferation domain,

What can you do to use your knowledge in electronics and communication to help people?

You can make websites to inform people such as this, creative.colorado.edu/~brgu1294/wearabletechnology.html or you can work as a consultant

What is the best method in collecting data?

the library is the best because it is all factual the Internet can lie and make you get answers wrong.

Can a CB radio pick up VHF radio signals?

No. The old Citizen's Band (CB) consists of several skinny channels between 27 and 28 MHz,

and that's where the receiver part of a CB transceiver operates. "VHF" is technically the range

of frequencies between 30 and 300 MHz.

Op-amp characteristics of ac and dc?

dc characteristics:-

1.input off set voltage,

2. input bias current,

Ac characteristics:-

1, commen mode rejection ratio,

2. slew rate

How do you identify the leads of a diode?

There are two wires on a diode: Anode (positive in) and Cathode (negative out). A diode may have a grey band at the cathode end, and black at the anode end. Diodes come in many sizes and capacities, some with clear markings, some without, so there are times when a multimeter has to be used.

Set the multimeter to the diode setting (looks like an horizontal arrow fired from a bow, with three lines meeting at the arrow-head's tip). Touch one wire with the red + probe, and the other wire with the black - probe. If there is no reaction, electricity is not flowing. Reverse the probes and you should get a reaction showing that electricity has been detected. So the red probe marks the anode wire and the black probe marks the cathode wire.

If there is no reaction, whichever probes are tried, then the diode is dead.

What are the role of cathode tubes in atom?

cathode tubes were used to detect the particle in an atom & found that negatively charged particles(electrons) are there in an atom.

Does resistor is a negative coefficient of temperature?

Actually it depends on the material from which the resistor is made, well in general for all practical purposes we choose a material with positive temperature coefficient as we deliberately want to add a resistance to the circuit.

But if we come across some resistors which are made up of materials like Glass, Ceramics, Semiconductors , have negative temperature coefficients (practically not used)

If each lamp is rated 12v 24w what is the current consumed by each lamp?

2 amperes in a parallel circuit. I = W/V. It is true provided that 12v are delivered to the lamps in parallel circuit. In a series circuit, the voltage is divided among the lamps so that the total current is probably 2 amperes for all lamps.

At what voltage do you need to use double locknuts on Rigid Metal Conduit?

There are no voltage regulations. A rigid conduit system used two locknuts and one bushing at every connection to a junction box unless the box has a hub. One outside the box and the other locknut inside the box. These are tightened against each other to make the connection secure and to scratch the paint on the outside of the box to make continuity of the metallic system. Continuity of the system is a must as this is the return path for any short circuit that might occur. Rigid connections to fittings require no locknuts as the conduit's threaded end screws into the fitting.

Thin wires have a what resistance to electron flow than do thicker wires?

Thin wires have a greater resistance rhan thick wires. Imagine a straw. The thinner the straw. the less liquid can get through. Wires work the same way.

How does a multiplexer operate?

Multiplexer is a generic term. Multiplexer can be anything that takes signals from several devices and sends the info through one channel. Usually demultiplexor is used on the other end to select the right device to send the info to. Does this help. Just Google it for more info. Good luck.

Is shift register edge triggered or level triggered?

If the shift register is synchronized (uses clock) the control signal is level triggered. If the shift register is asycronized (no clock) the control signal is edge triggered.

What is a PID controller?

A proportional-integral-derivative controller(PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the error minimal.

Why does the television need to be connected to the isolation transformer before it is connected to the power source?

Television sets do not need to be connected to isolation transformers for normal operation. However, most modern sets do not have power transformers, which means they run directly off of the line. In that case, you do need an isolation transformer to protect yourself from electrocution during repair.

Is An open in the main line of a parallel circuit causes all individual branch currents to be zero?

Yes, an open in main line of a parallel circuit will effect the entire circuit current and make the whole circuit current zero
