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.

How do you implement 8-bit comparator using two 4-bit comparators?
set the < , =, > as "010" and connect the lower bit that you want to compare to the first comparators and connects its output to the input of second comparator like this; connect the P<Q to < , and P=Q to = and P>Q = > (cascading input is checked for when P and Q are equal; the input from cascading input is set to the output "010"
What are the applications of CMOS?
cmos technology is used in low power applications in vlsi and also used in image processing.cmos inverter has many applications like oscillator,amplifier and also used in analog transmission,digital applications etc.,
What kind of material are in most conductors?
Most conductors contain metals. These provide the free electrons, which can pass a current.
What is the difference between conductivity and mobility?
conductivity and mobility both are directly propertional
Why light emitting diodes are good?
LED (light emitting diode) is an electronic component that generates light from the electrons flowing in one direction through it, in an electron circuit, possibly as part of a circuit board. In a circuit the light emission can be a short as a nanosecond. One or more LED's can be used to make light with a minimum of electricity. Modern applications are wide spread including optical sensor activators, calculator displays and automotive tail lights. LED's have come down in price and can last for tens of thousands of hours so have become an economical replacement for other lights in some applications.
Who is the father of electronics communication?
For wireless communication, undoubtedly Guglielmo Marconi, who invented the spark gap transmitter. Then for telegraphy, it has to be Samuel Morse. The telephone was invented by Alexander Graham Bell.
How many type of electric circuit?
There are basically two types of circuits: parallel and series. In a series circuit, current flows in one continuous straight path. In a parallel circuit, the current has more than one path to follow.
Answer
There are four categories of circuit, not two. These are 'series', 'parallel', 'series-parallel', and 'complex'. A 'complex circuit' describes any circuit not falling into the first three categories.
Why an inductor acts as a conductor?
Resistors and MOSFET/ transistors are two different animals, sory but
What is the effect of emitter resistance in common emitter amplifier?
The gain of a common-emitter amplifier is collector resistor divided by emitter resistor, or hFe, whichever is less. Since hFe depends on temperature, designing the amplifier to be dependent on resistance ratio makes it more stable. As such, the emitter resistance serves to stabilize the amplifier.
Solder is a metal ,specially alloyed to be used to fix or weld together other pieces of metal.
How to use it would depend on the application and the exact metals being used
According to Ohms law, which states that Resistance (R) = Voltage (V) / Current (I)
6 Ohms
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
A: If you know the total resistance and total voltage then you know total current flow for the circuit, this current will be same for every resistor in series however the voltage drop will change for each resistor . So measuring the voltage drop across the resistor in question and divide by the total current will give you the resistor value.
Why resistor is an electronic device?
electronic circuits are those which deals with flow of electrons. in general electronic devices are categorized based on the flow of e as conductor, insulator and semiconductor. since resistor resists the flow of electrons (it deals or works with electrons), it is consider as an electronic device.
Why is collector reverse biased?
to prevent direct conduction from base while collectingminority base carriers from emitter that "overshoot" the thin base.
Defination of pn junction with diagram?
A PN junction is a semiconductor interface formed by joining p-type (positively doped) and n-type (negatively doped) materials. This junction creates an electric field that allows current to flow in one direction while blocking it in the opposite direction, functioning as a diode. The p-side is rich in holes (positive charge carriers), while the n-side contains electrons (negative charge carriers).
Here's a simple diagram representation of a PN junction:
P-type | N-type
+----+ | +----+
| | | | |
| | | | |
+----+ | +----+
In the diagram, the '+' symbols represent holes in the p-type material, and the '-' symbols represent electrons in the n-type material.
Would a solar-powered receiver transmitter work on the moon?
As long as the solar cells powering the transceiver (transmitter/receiver), that device should work on the moon.
What are the functions of a gate keeper?
The term, gatekeeper, means a person that tends, or stands guard at a gate and controls who goes through the gate. A gatekeeper is usually found at huge property entrances with gates, either personal property or public buildings like museums.
