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.

It would be the sum of the two resistances, as they are connected in series.
Thomas Edison described the concept of simulating motion in 1888, and his associate William Dickson created a practical device by 1892.
How do YOU USE a decoder ring?
A decoder ring is usually a type of substitution cipher, it switches each letter in a message with a different letter or character, thus making the original message unreadable. The person receiving the scrambled message must have a key or the same decoder ring to translate the message back to plain text.
It can be a simple computer program, but is more entertaining when it is an actual ring or disk to encode/decode messages.
What is the difference between a half wave rectifier and a negative clipper?
As far as general principles apply, they both perform the same function: using a diode.
Which ic you can use instead of ic 4017?
CD4017 is a CMOS decade counter. The only thing that can replace is another CD4017 because it uses a rather unusual high impedance high voltage (28 volts) technology. They are readilly available.

someone please tell me what an analogue connection is...:(
Does a walkey talkey with frequency 462.55 MHz to 467.71 MHz would work in India?
It should work... just as long as a receiver is nearby with the same frequencies. Any radio will transmit anywhere. it's just that nobody will hear it unless they are on the same frequency and within hearing range.
What happens if we sample the signal at sampling frequency nearer to signal frequency?
If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.
Slipping alternator belt
Loose connection
Bad alternator
Computer problem
its for something known as "time pass"
no good reason...just there
=)
both S and R go high at the same time..this may lead to oscillation or an invalid set
Why phase modulation is least used?
Actually phase modulation was used for the color signal in all analog TV systems.
Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.
Certain modems use phase amplitude modulation.
etc.
Why the arrow mark in emitter is base in ujt?
In a Unijunction Transistor (UJT), the arrow mark in the emitter symbol indicates the direction of conventional current flow when the device is forward-biased. The emitter (E) is the terminal where current flows out, and its arrow points toward the base region, which is the junction where the UJT operates. This configuration helps identify the emitter as the terminal that controls the device's operation, distinguishing it from the base and preventing confusion in circuit diagrams.
Is placing voltmeter in series dangerous?
Yes, placing a voltmeter in series is dangerous because voltmeters are designed to measure voltage across components and have a high internal resistance. Connecting them in series can cause excessive current to flow through the meter, potentially damaging it and creating a risk of electrical shock or fire. It is important to always connect voltmeters in parallel with the component being measured to ensure safe and accurate readings.
Back in 1935 what was clarence elder childhood like?
Really sad, his parents moved away when Clarence Elder was only five years old.
What is Excitation resistance?
It is a Photosystems Excitation Pressure and Development of Resistance to Photoinhibition. The investigation revolves solely around comparing resistance increase.
Can you get FM broadcasts on a VHF receiver?
If you're referring to commercial FM "music, news, and talk" broadcasts, the answer is 'No'.
Those stations all transmit on carrier frequencies between 88 MHz and 108 MHz. Your VHF receiver
most likely doesn't cover those frequencies.
Even if it does overlap the commercial FM band, at the end of its dial, the VHF receiver won't deliver
anything worth listening to.
A). It's basically an AM receiver, not FM.
B). It might deliver a recognizable voice from a narrowband FM signal, but it isn't designed to
even admit the comparatively wide-band commercial FM signals.
What do you mean by sample and holds in DA and AD converters?
DA means conversion of digital data into analogous and AD means conversion of analogous data into digital one.
