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.

Why d flip flop called as delay flip flop?
"D" in D flip flop stands for "delay". It basically means that the "D" value is not read immediately, but only at the next positive clock edge.
How is electrical contacts installed on an MS connectors?
Normally, wires are connected to MS connectors via soldering [on aircraft as far as I know, although I am trying to find out about other methods].
Can you use a 9.6 volt battery instead of 7.2 in toy car?
You could, however you may damage the electrical components in the car. The motor, wiring, speed controls etc. are all engineered to operate at the specified voltage. If you want to go faster for a short period of time the higher voltage will do that for you.
a personof vision is someone who has an idea to help many people and works on it making it a reality
Can you use two horizontal amplifier and one one vertical amplifier in dual beam CRO?
I think you'd want just the opposite. The sweep rate is the same for both
beams, so you only need one set of horizontal deflection components. But
the vertical amplitudes of the two signals are generally different at the same
instant of time, and you want to keep the two signals separate and distinct,
so you want them running through two different vertical amplifiers.
Pink noise is noise in which the spectrum density is proportional to inverse of the frequency. It is also known as 1/f noise.

Why the light circuit is separated from the power circuit?
depending on the size of the house you could end up with needing a huge fuse. so it's a logical split. you could have each room separate if you wanted or every single switch. you'd just need a huge fuse board.
also having the lights and power separate means that if one goes then you have the other to provide light.
not really any other reason than the fuse one really.
Q = CV,
Q is charge,
C is capacitance,
V is voltage.
C= Q/V
= dQ/dV since it is linear function
= 0.41F
HLR is the Home Location Register for GSM and CDMA wireless networks. It is responsible for the authentication and authorisation of subscribers and their services.
due to reflecting torque pointer moves in one direction by due to controlling torque pointer moves in opposite direction therefore pointer oscillate in forward and backward direction.if there is no deflecting torque the device to ensure that the pointer comes to rest quickly with minimum oscillation at its correct reading position is known as damping device...
The BSc is just another abbreviation for a bachelor of science degree. Other abbreviations for the same degree are, BS, ScB, SB depending on the institution. Most US schools indicated it as a BS.
Why two independent sources cannot behave as a coherent sources?
Light is emitted due to the de-excitaton of electrons from higher orbits of the various atoms of the light source.The de-excitation can also be to different levels in different atoms resulting in emission of different wavelengths.A light source will have numerous atoms in it.When you take two light sources it is not possible for all the atoms to get de-excited to the same shell at the same time(causing phase difference) that is why two independent sources cannot be coherent.
How is applied electronics and instrumentation course different from instrumentation and control?
but instrumentation and control are concerned with the control system and the process loop modelling e.g: power drives , linear and non linear control system
How do you convert cellphone gsm frequency to another gsm frequency?

What happens when a inductor is energized?
the current is raped from it's present to some a new value .
Expanding or collapsing magnetic field units a cross coil and induces a voltage that opposite di/dt
DSTATCOM is one of the equipments for voltage sag mitigation in power systems. In this paper a new control method for balanced and unbalanced voltage sag mitigation using DSTATCOM is proposed. The control system has two loops in order to regulate
compensator current and load voltage. Delayed signal cancellation has been used for sequence separation. The compensator should protect sensitive loads against different types of voltage sag. Performance of the proposed method is investigated under different types of voltage sags for linear and nonlinear loads. Simulation
results show appropriate operation of the proposed control system.
Why CE transistor is more temperature senstive than CB transistor?
In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.
When voltage increase then current will be?
it depends on what type of load. Motor amperage will drop off as voltage rises. loads such as lights will increase amperage with voltage rise.
What happens when the voltage standing wave ratio is too high?
If the vswr (Voltage Standing Wave Ration) is high than call drop chance increase.
What is the flaw of ECL logic family?
The main limitation on the use of Emitter Coupled Logic is that it is very very power hungry, so the devices tend to require a significant cooling system to remove the waste heat. But in most systems where the speed advantage offered by Emitter Coupled Logic is deemed a necessary requirement, this is usually considered a minor price to pay.
