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.

What is Bilbo?

Built in logic block observer. It is used in Built In Self Test (BIST) of digital circuits. It provides the capability of test generation and compressing the output, for a circuit.

Can items in a series circuit be in any order?

Yes. The arrangement doesn't change the current through

the circuit, or the voltage acrosss any individual component.

Why RC coupled amplifier is called audio amplifier?

Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.

What is the space wave propagation frequency?

Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question

What is the significance of packet size in a packet switching network?

The packet size is important because the network can then allow for flow control via a pre-determined 'window'. If there is a lot of PDUs travelling, the network can slow down the flow control, and reduce the packet window - so the receiving end can keep pace with the transmission - in an attempt to avoid a slowdown in network performance. However, in some instances the packet size can be set so that it cannot be fragmented.

What is toggle bit?

when dealing with bit, there are only 2 bits which are '0' and '1'. when the current bit is '0', if we toggle this bit, it will become '1' and when the current bit is '1', if we toggle this bit, it will become '0' that is

What is filter rejection?

Its when someone blocks off acess to areas such as i want to go on youtube but you cant because they blocked it off. To unlock you must unlock it with your computer manuel instructions each computer has there on instructions hope this helped

1993 Toyota Camry ac amplifier location?

Take out the glove box, it's a black plastic box screwed to the tubular frame.

Where can you find a live feed of an internet police scanner?

You can listen to over 100+ live feeds from across the U.S. at: + Live Police Scanner Audio Feeds

What is the symbol for diode?

The symbol for a diode is a horizontal line with an arrow pointing to an intersecting vertical line, the horizontal line continues on the other side of the vertical line.

What is the Effect of quiescent point close to cutoff?

The output voltage swing will not reach its maximum. This would then give clipping of one side of the signal which means the signal output is not a amplified representation of the original signal.

What are the primary and secondary telecom cable color codes?

Primary: blue, orange, green, brown, slate

Secondary: white, red, black, yellow, violet

What is the line diagram symbol for a mercury tilt switch?

The diagram symbol for any tilt switch is the ball tilt switch symbol.Then in the table of contents the switch is described,whether it be a ball switch,mercury switch,etc...

What is ac and DC current?

AC stands for alternating current and means that the current changes directions, flipping repeatedly from positive to negative and back again.

DC means direct current, the current only flows in one direction and does not change polarity.

Explain why diodes melt?

Diodes, like many other electronic/electrical components, will melt if the temperature is high enough. This would occur if the power dissipation were too high because the current was too high.

Why doesn't the primary winding on a transformer have a neutral?

In a three phase transformer, the primary winding is often configured in a Delta. The delta winding configuration does not use a neutral. The secondary winding is often in a Wye configuration, which does have a neutral.

The Delta configuration is typically used for transmitting power to various locations, and thee phase loads where a neutral is not needed. The Wye configuration is typically used to distribute power in a facility where there are single phase loads that need a neutral.

There are other reasons to use either Wye or Delta, such as grounding issues, but I think the short answer is probably what you're looking for (I hope).

Hope this helps!

Why is the electric watt meter connected in series with the rest of the circuits in the house?

First of all, you are referring to an energy meter, not a wattmeter. A wattmeter measures power, in watts, whereas an energy meter reads energy, in watt hours (or, more specifically, kilowatt hours). The energy company bills you for energy, not power.

Having said that, the connections each instrument are the same. In fact, there are two coils inside an energy meter: a current coil, and a voltage (or potential) coil. The current coil is connected in series with the load while the voltage coil is connected in parallel with the supply voltage.

The current coil measures the in-phase component of the current drawn by your load, so that the instrument always reads the true power (multiplied by time -the function of the aluminium disc) of the load -i.e. not the apparent power or reactive power.

Since when has fixed capacitor have been seen in use on transmission line?

Capacitors have always been added on both power lines and telephone lines to compensate for the build up of inductive reactance in long runs of wire.

When testing for current draw your digital multimeter should be set on?

When testing the current draw your digital multimeter should be set on the current.

Which cicuits light the bulb better-Bulbs light better in which kind of circuits?

If you are comparing parallel vs series circuits, light bulbs produce more light in parallel circuits.
