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 the meaning of TOD meter in electrical engineering?
60 minutes, 30 minutes or 15 minutes Time of Day (TOD) : Up to eight, seasonal, time of day rate registers for energy and demand Power factory : Recording of average monthly power factor.
What is a joule and what does it measure?
he joule is the unit of energy in the International System of Units, also known as SI. It measures heat, electricity and mechanical work. It was named after English physicist James Prescott Joule. See the related links for more information.
The joule is a derived unit equivalent to a newton-meter, or a kilogram-meter squared per second per second.
A joule is also:
- A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for a period of time of one second.
- A unit of energy equal to the work done when a force of one newton* acts through a distance of one meter.
[* In the meter-kilogram-second (MKS) system, a newton is the unit of force required to accelerate a mass of one kilogram one meter per second per second, equal to 100,000 dynes. The unit is named after Sir Isaac Newton.]
What is rf diversity receiver?
it is applied at receiving end of antenna for reducing interference.it uses selective combiners to combine two corerelated signals
What are elements that are shiny bendable and good conductors of electricity called?
Metals.
The elements that are classified as "Transition Metals" and are located in Groups 3 - 12 of the Periodic Table are elements that are shiny bendable and good conductors of electricity.
What is instrumentation commissioning?
Instrumentation commissioning is the total engineering services necessary to test a process plant instrumentation before it is transfered to operation. Comissioning services include calibration of instruments, solution of puch list items, loop tests, configuration of flow computers, documentation and other associated services.

What is advantage of split muff coupling?
1. Muff Couplings have a high torque capacity and zero-backlash. They suit
applications when misalignment is neither present or desired.
2. It can be removed or disassembled witout disturbing the shafts.
What is the base spreading resistance?
base spreading resistance is the resistance which occur at the base of transistor dis is becoz of varying base voltage
What is the minimum voltage required to turn on a pnp transistor?
If it's a germanium transistor, 0.3 volts. If it's the more common silicon transistor, slightly more than 0.6 volts.
Metal Oxide Semiconductor. Usually used when referring to a specific type of transistor which uses this type of semiconductor material: the Field Effect Transistor (FET).
Pls tell you if the admission list for futo is out?
why is it that many universities in the federal have resumeed lectures only federal university of technology owerri haven't, why? please tell me i want to know. or do they think that we are foolish for chosing them as our first and second choice?
What are the advantages of digital modulation over analog modulation?
1)digital modulation can easily detect and correct the noise. where as analog modulation has little complexity 2)security is more in digital modulation 3)digital modulated signal can traverse a long distance compared to analog modulation
Why gate circuits are isolated from the main circuit?
Gate circuits should be isolated from the main power circuit to avoid any damage to the power circuit if gate is damaged.
hPa is a hectopascal. It is the equivalent of 1 x 10^2 Pascals.
What are the advantages of buying a well-known brand name computer?
A well put together machine and after sales support.
IC 7485 is a 4-bit magnitude comparator.It takes two nos in 4-bit binary format and compares the nos as to if they are equal or which one is greater.
Why has the midi have a wide range of frequency?
i doesn't have the widest range the synthesiser does
series reactor is used to limit the fault current. b'cos reactor contains inductance and it opposes the rate of change of current
Why full adder is better then half adder?
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
commissioning...its inspecting a piece of equipment or plant to make sure you got what you paid for...i.e. the vendor build the correct thing...part of it is making sure it is safe to start up. This can be done by comparing the as built to the drawings.
