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.

No, you cannot amplify gravity. It is a function of mass, and a certain mass exerts a certain gravity at a certain distance from the center of mass. To increase gravity, you need to increase the mass or shorten the distance.
(Note that should you move "within" the mass, you create an entirely different circumstance.)
Will lights in a series circuit will stay lit if one goes out?
Like the old Christmas tree lights, no; lights connected in series will not stay lit if one (or more) are either burned out or disconnected from the circuit. Lights in series are connected "head-to-tail". Take one out, and the circuit is incomplete and will not work.
Why In Clippers And Clampers 0.6 Volt Is Reduced?
.6v is the peak inverse voltage drop of a silicon made diode.
ANSWER: A diode will have a .6 to .7 volts drop [depending on current] in the FORWARD conduction mode. In the inverse it could be 50 to 1000 volts depends on the diode.
An ordinary diode, no. It has nowhere to get energy from.
But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.
What are the arguments against FDI in retail?
- FDI will lead to job losses. Small retailers and other small 'Kirana store owners' will suffer a large loss. Giant retailers and Supermarkets like Walmart, Carrefour, etc. will displace small retailers.
- Supermarkets will establish their monopoly in the Indian market. Because of supermarket's fine tuning, they will get goods on low price and they will sell it on low price than small retailers, it will decrease the sell of small retailers.
- Jobs in the manufacturing sector will be lost because foreign giants will purchase their goods from the international market and not from domestic sources. This has been the experience of most countries which have allowed FDI in retail. Although, our country had made a condition that they must source a minimum of 30% of their goods from Indian micro and small industries, we can't stop them from purchasing goods from international markets as per WTO law. So after coming to India, they can reduce this 30% by litigating at the WTO.
· Allowing foreign players could destroy the livelihoods of millions of small store owners
· Market prices could be manipulated by foreign retail giants
· Local jobs could be at threat since the foreign players could purchase many products from abroad
· There is no established correlation between advent of FDI and improvement of a country's infrastructure
What can you measure with amperes?
Current is measured in amperes. Amperes is also coulombs per second.
As current flow trough a wire by using the right hand rule of thumb a magnetic flux encircles the wire. if an adjacent wire are passive these lines of flux will generate an electron flow on that wire therefore the transfer is complete minus the efficiency of the transfer . Magnetics LINES varies as the square of the distance.
Do you need an education to work for UPS?
No, you can load the trucks without having to go to college, higher than that I'm not sure.
What does PLC mean in electrical?
PLC stands for Programmable Logic Controller. Basically its like a small computer that uses simple logic to execute automated processes, like in a factory. Lets say there is a factory that test balls for color. The desired color is Red and any other color is discarded. With the help of senors, the PLC will determine if the Ball is of Acceptable color and either trigger a sequence that transfers the ball to a different location, or kicks the balls of different colors out from the Passable balls. There are many types of PLC's. Some examples are SLICK 500 and Allen-Bradley. How ever this is only a small example of what PLC's are capable of doing.
What happens when current flows where it isn't supposed to?
When current flows where it isn't supposed to there is a lot of arcing and sparking. In an electrical circuit what the current is trying to do is get back to the source any way it sees fit using the path of least resistance. This is where over-current devices (breakers and fuses) come into effect to stop the fault and prevent the least amount of damage to the equipment as possible. It is well documented the damage that the current from a lightning strike can do and there is no over-current device in the world that can prevent it from happening.
On the lighter sideThat's a very serious thing. It is sent to bed without its supper.

What is a path through which current flows?
A path through which current flows is generally called a circuit. Some might say a complete circuit to denote a "closed loop" through which electricity can leave one electrode or contact on a voltage source, travel through some conductors of some kind, and then return to the other electrode or contact on the source.
There are many different instructions and registers in the 8086/8088. The question is too broad. Please ask a more specific question. Alternatively, you can consult a good book, such as "The 8086/8088 Primer", Second Edition, Stephan P. Morse, Hayden Book Company, or any of a wide variety of other books.
Which diode do I use for a 12V 7A battery to make the current only flow one way?
You need at least a diode with a current limit of 7Amps. Best to use a 10A or more, to allow a little headroom. You are using it as a blocking diode and will therefore want a low forward voltage drop. The best type for this is a schottky type and as it is going to supply a high forward current you will need proper heat sinking.
The best one I can find is a type MBR1435CT
This is in a TO220 package with a heatsink tab on it.
Transformers are devices that use the principle of coupled magnetic fields to step voltage up or down, or provide DC isolation in circuits. A signal transformer is a special application of a transformer that is used to couple a signal from one circuit into another circuit. The signal might be stepped up (or amplified), or it might be stepped down, or it might be coupled without an increase or decrease simply to provide isolation, impedance matching, or phase shifting from stage to stage in an electronic device.
LEDS are more reliable than lasers because they operate at lower frequencies therefore do ot suffer any catastrophic degradation or even gradual degration prevalant in laser
How many types of field effect transistor?
There are two types of field effect transistors:
- junction field effect transistors and
- metal-oxide semiconductor field effect transistors.
Bulbs are things that are plugged into light sockets, and they light up when the electricity is turned on.
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.
