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.

When one resistance or load in a series circuit gets defective the circuit becomes?
The circuit will become an open circuit.
What happens to a light bulb when put in series with a inductor?
When you put a light bulb in series with a inductor, the inductive reactance of the inductor reduces the current available to the light bulb, making it less bright.
For this effect to be noticed, however, you need a very large inductor. To cut the current in a 60W bulb at 120VAC/60Hz by one half, for instance, you need an inductor around 0.6 henrys.
How do you connect a motor to a picaxe 18M?
It depends. If you only want to turn the motor in one direction, then you could simply use a medium power mosfet (eg:IRF530) connected to an output pin on the PICAXE, and with a backward diode around the motor.
If you need to change direction, it's best to use an L293D, which allows independent bidirectional control of two motors.
What is locator in embedded system?
by contrast creates file that will be used by some program the copies the output to the target system later the output from the locatar will have to run on its own.
gautam and arunesh.
What is current gain and voltage gain?
Current gain is the ratio of output current divided by input current.
Voltage gain is the ratio of output voltage divided by input voltage.
Nothing more complicated than that.
The voltage must reduce by the same factor - that is Ohm's law.
How many things are needed to create a current?
A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.
Is quantize one of the stages occurring in the process of analog digital conversion?
Yes. The stages are Sampling, Quantizing and Encoding (in that order)
The energy leaves as either a photon or phonon.
How do you say flip flops in spanish?
Most Spanish speaking people use the term "Chanclas" to refer to Flip-Flops, which simple means "sandals"
What device convert a signal from binary or analog form into a signal of another form?
Transmission Media
A common-source (CS) amplifier is a type of field-effect transistor (FET) amplifier configuration that provides voltage amplification. In this setup, the input signal is applied to the gate terminal of the FET, while the output is taken from the drain terminal. It is characterized by its high input impedance and moderate output impedance, making it suitable for interfacing with high-impedance sources. The CS amplifier is widely used in analog circuits due to its simplicity and effectiveness in amplifying signals.
What is the basic principle of ADC?
simple comparator technique.
An analog-to-digital converter (abbreviated ADC, A/D or A to D) is a device which converts a continuous quantity to a discrete time digital representation.
What is the unit of measures for resistors?
Resistor values are given in ohms. A value may be selected to deliver a specific current at a given voltage. This is given in what is known as Ohm's Law where:
Voltage (V) = Current (A) X Resistance (Ohm)
A 12ohm resistor placed across a 12V battery would pass 1Amp of current and put out 12W of heat.
How will you get registration for pwd pune?

How do you know when your capacitor is charged and ready for hook up?
The capacitor charges up when you initially install it and apply 12 volts to the circuit. Its purpose is to smooth out power drops in the 12 volt supply line to the amp. For instance, when the bass hits the speakers, the amperage surge can exceed the amperage the line delivers for a split second, so the capacitor supplies amperage briefly to sustain the power.
Hooking up a small motorcycle battery close to the amp serves the same purpose but is possibly messier because of the potential to leak acid.
If the frequency in AM does not change then how are these sidebands formed?
The process of changing the amplitude of the "carrier" so as to add information to it (modulation) doesn't change the frequency of the carrier. But it does create energy at two other newfrequencies.
The new frequencies are equal to (carrier frequency) plus and minus (the modulating frequency). These are referred to as the upper and lower sidebands.
The upper sideband is an exact copy of the modulating signal, but with every component of it shifted up by an amount equal to the carrier frequency. The lower sideband is a mirror image of the upper sideband, with every frequency component in it reflected about the carrier frequency.
A resistor is a device that resists, or limits, the flow of electric current through itself. The more resistance a thing has, the more it limits current (at the same voltage). In a circuit, resistance and current are inversely proportional. The more the resistance, the more current will be limited and the less current will actually flow. Resistors pay a price for limiting current - they create heat.
In other words, resistors convert electrical energy into heat energy.
It might be convenient to divide resistors into just two groups for this discussion (though there are many possible ways to catagorize them). Resistors might be though of as electronic components, or as thermal elements in a device or equipment. A resistor "sorta" conducts current flow, but it heats up as a consequence to having current "forced" through it by some applied voltage. If the resistor is an appliance, it is probably being used specifically to generate the heat, because the heat is what is desired. We need to dry our hair, or the clothes. We want to make toast or coffee or bacon. Incandescent lights could be seen as resistors, but we don't (usually) use them to generate heat. Heating elements, or thermal elements, are heaters - resistive heaters. In electronics equipments, resistors are included in circuit designs to "develop" voltage and to limit current. They are an integral part of the electronics world, and anyone entering in will be seeing them and solving a number of problems with resistance, current and voltage within a short time of arriving.
