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 fuse 13 A in a plug is intended to?
This is intended to protect the flex of a plug.
A fuse is a little wire that all of the electricity coming into the appliance flows through.
If something goes wrong and the current is higher than it should be, this fuse will overheat and burn out, thus breaking the wire and cutting the flow of electricity. If there was no fuse, the circuit would not be broken, this could overheat the plug and it could possibly catch fire.
The 13A means that that fuse is set to 13 Amps of current, If it gets anything over that, the fuse will blow. Depending on the appliance the number will vary. 13A fuses are mostly used in the flexes of an appliance that have a high voltage, such as heating appliances like kettles fan heaters. When choosing a fuse for a plug you must choose a fuse that is higher than the current that the appliance has as current is higher when things are first switched on. If you choose a fuse that is too low for the appliance, the fuse will keep blowing out. Never choose a fuse that is too high for an appliance as this will not blow out if the current is too high.
What action results in an ampere of current?
MOTION OF A CHARGE (1C) IN A TIME OF 1S RESULTS THE AN AMPERE OF
CURRENT TO FLOW..... on a broad way
I= q/t
q=ne
so I= ne/t
so put e = charge of electron, t=1s I= 1A then u will get how many electrons are flowing to constitute the current of 1A (e= 1.66 X 10-19 (-19 is in rays to power of 10)
Who discovered the p-n junction?
The p-n junction was discovered by Russell Ohl. A p-n junction is boundary between two types of semi-conductor material. One can find more information on a p-n junction on Wikipedia.
What are the types of computer according to size?

- Mainframe --- commercial information management, data storage and processing
- Supercomputer --- scientific research, intensive data processing (e.g. military logistics, weather forecasting, astronomy)
Which is the Direction of the current in resistor?
A resistor is bi-directional meaning current can flow in either direction. Current flows from positive to negative.
What determines the transformer ratio?
Transformer ratio, more correctly turns ratio, is the number of turns in the primary winding divided by the number of turns in the secondary winding.
Front-end and back-end design?
People who do coding comes in Front end design and remaining comes in backend ..........
Front end includes rtl description,synthesiser,verilog/vhdl entity,simulator.....
Back end includes floorplanning,place & route,packaging,testing...
When using series-opposing voltage sources?
of course...by connecting parallel resistor to it ,,so when v look from load end there will b a voltage as well as resistance same to that of voltage source..
How many amps will a 260 ohms resistor on a 120 volt circuit use?
Just use Ohm's Law
Voltage = Current x Resistance
Amps = Voltage Divided By Resistance
Amps = 120 / 260
What are the disadvantages and advantages of parallel circuit?
Abraham Lincoln preferred them to perpendicular circuits.
25*80 = 2000 JOULES
30 volts.
What is formed when part of a material is doped n-type and part of it is p-type?
if the two parts are next to each other, a junction. if not, nothing.
Why is it important to band limit a signal before sampling it?
Band limiting a signal before sampling is crucial to prevent aliasing, which occurs when higher frequency components of the signal are misrepresented as lower frequencies due to insufficient sampling rates. According to the Nyquist-Shannon sampling theorem, a signal must be sampled at least twice its highest frequency to accurately capture its information. By band limiting, we ensure that only the relevant frequency components are present, allowing for accurate reconstruction of the original signal after sampling. This helps maintain the integrity and quality of the sampled data.
What is the Clipping circuit transfer function?
Transfer function is the relationship between output and input of a circuit. In the clipping circuit, the general transfer function is such that the transfer curve Av is less than 1 for passive limiter and greater than 0 to limit the maximum and minimum voltage value.
Is continuous signals has no amplitudes?
By definition a continuous signal is just that continuous to have no amplitude is to mean it doesn't exists
What is bifference between optical bandgap and semiconduct0r bandgap?
we all know that electrons,photons, phonons can excite an electron from valence band to conduction band...i think the main difference between electronic bandgap and optical bandgap is that in electonic its the energy required for an electron to move from the valence band to the conduction band.but in optical bandgap photons(packet of energy in the form of light waves) are assisting the electrons to move from valence band to conduction band.
The difference between optical and electronic bandgap is more complexe actually. The optical bandgap is the one that can be measured using optical techniques (based on transmission and reflection, i.e. Tauc plot). However, this measurement does not take into account all traps you might have within the bandgap that can modify the energy required to move one charge carrier from the conduction band ans the conduction band. The electronic band gap (which is the one of interest in fine, in an integrated device) is measured under operation. Thus, for many devices (lasers, solar cells...etc.) the electronic bandgap (energy required to get the device working) can defer from the optical bandgap.
Forward bias and reverse bias?
- forward bias is in the direction a junction or vacuum tube wants to conduct current
- reverse bias is in the direction a junction or vacuum tube opposes conducting current
How do obtain wiring diagram for comenda c155bt dishwasher?
In UK you can send an email to: service@dawsonmmp.co.uk. Regards.
What is Gaussian low pass filter?
Gaussian low pass filter is a image smoothing filter which is used to smooth up a digital image...........
Point three three or 1/3rd of a volt will power any piece of equipment that is designed to operate on that voltage.
To put it into perspective 1 volt = .33 volts x 3.
What is the equalent value of 7440 ic?
The equivalent value of 7440 IC, which refers to the 7440 integrated circuit, is typically a quad 2-input NAND gate. It can be replaced with other similar logic gate ICs like the 74HC00 or 74LS00, depending on the specific requirements for speed and power consumption. These ICs are part of the 74 series of digital logic families.
