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.

There can be no answer for this without knowing how strong a resistor is involved. (Ohms)
How vhdl acts as an exchange medium between chip vendors and cad tool users?
CAD means computer aided design. CAD tools are used to design chips virtually on a computer. Programming languages like VHDL, Verilog, System C, Syatem Verilog are used for this purpose. The successful designs of these languages can be fabricated into chips.
How did the amplifier get its name?
Answer 1: From the word amplfy, which is transitive verb me:ning
1 : to expand (as a statement) by the use of detail or illustration or by closer analysis
2 a : to make larger or greater (as in amount, importance, or intensity) : increase b : to increase the strength or amount of; especially : to make louder c : to cause (a gene or DNA sequence) to undergo amplification
Answer 2: The word "amplifier" is derived from the word "ample" which, in turn is derived from the Latin word "amplus" meaning full or plentiful or generous in size. Any part of the electromagnetic spectrum can be amplified, but the term usually refers to the audible spectrum (20 - 20,000 hertz) where the sound is made greater by an amplifier.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand...
Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit.
For resistors in series: RTOTAL = R1 + R2
For resistors in parallel: RTOTAL = R1R2/(R1+R2)
What happens if you connect two transistors parallel?
If you connect two transistors parallel it will heat up and be damaged.
What is meant by open circuit voltage and arc voltage?
Open circuit voltage refers to the voltage measured across the terminals of a circuit when no current is flowing, indicating the maximum potential difference available. In contrast, arc voltage is the voltage present across an electrical arc, which occurs when a current flows through a gas or air gap, creating a conductive plasma. Arc voltage is typically lower than open circuit voltage due to the energy losses associated with the arc's resistance and ionization. Both concepts are crucial in understanding electrical systems and their behavior under different operating conditions.
What is PAD in Audio application?
It is either:
- Pad button, that is found on some preamps and it is used for lowering input gain, usually by -20dB.
- Synth pad, that is a a sound used in electronic music which is a harmonic background sound
If the gain of the open loop system is doubled then gain margin will become?
gain margin becomes half
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
What happens if you use a fuse that's overrated for voltage but has the correct current rating?
Using a fuse correctly rated for current but "overrated" for voltage does not present a problem. Current ratings are critical safety issues, and fuses should be replaced with those of the same current rating. But using a fuse with an identical current rating but a higher voltage rating is not a problem. The reason for that lies in what the voltage rating of a fuse is.
Fuses are given a voltage rating to state a maximum voltage in a circuit that they are designed to protect. And the voltage rating has nothing to do with the "normal" operation of the fuse. The fuse carries current when it operates normally, but when something happens and excessive current flows, the fusible link heats up and opens. This is where the voltage rating comes into play. It is possible that a fuse can arc through when it fails. It is the voltage rating that stands in the way of this.
As long as the voltage rating of a circuit is not beyond the voltage rating of the fuse, that fuse will fail safely when it fails. It is acceptable to use a fuse of an equal current rating but a higher voltage rating when replacing a fuse that has failed.
Difference between Sr flip-flop nand gate and Sr flip-flop nor gate?
The nand gate variety of the SR flip-flop uses falsevalues to change state with, while the nor gate variety of the SR flip-flop uses true values to change state with.
What is a programmable logic ASIC?
Programmable logic ASICs is a classification of ASICs are programmed by blowing fuses in a device to alter the logic function.
Where did the word ohm come from?
Named after Georg Simon Ohm (1789-1854) German physicist who discovered the relationship between voltage, current and resistance in an electrical circuit
What is the frequency of the ac sine wave?
The frequency of any alternating current (ac) electrical supply always depends on the frequency at which the supply has been generated.
That is true no matter whether it was generated at a power station, for use in a home or factory, or in a dc-to-ac power inverter unit, for use in, say, a vehicle or boat.
Power stations in USA, Canada and other countries generate ac at 60 Hz.
Power stations in countries in Europe and other world areas generate ac at 50 Hz.
"Hz" is short for "hertz" which is the name used internationally for "one cycle per second".
