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.

Telmann washing machine fault E2?
You can contact Telmann in New Zealand on 0800 24 24 37 or (04) 415 6000.
What are three requirement for connecting the transformer in paralle?
Transformer capacity (kvA) shall be identical, Both transformer impedance, secondary voltage and frequency shall be identical.
The voltage would 9V minus any drop in the battery.
What is Microwave Gunn oscillator?
Gunn oscillators are widely used in the microwave to Terahertz region.
This uses a metallic coaxial cavity (in effect, a short length of co-axial cable) to provide the resonant effect which has been modelled earlier as an LC circuit. Although it looks very different, the oscillator shares with a laser the use of a cavity. The size of this cavity determines the time/phase delay which sets the resonant frequency. In this case, each diode induced fluctuation travels up the cavity and reflected from the far end, returning to the diode after a time
How can you tell which is the gate terminal on an SCR?
Since the gate needs very small amount of current for operation the small terminal is the gate.
If A is causally related to B, then it means that A has caused B.
A preset resistor also known as a poteintometer is a type of resistor whos resistance is selected by the user. A preset maybe of any range i.e. from 1k to 100k or from 1M to 100M.
a preset is used in many circuits where varyin resistance is required
How you will determine hazard in combinational circuit?
hazards in combinational and sequential circuits
What is the function of Max232?
The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F
voltage levels from a single 5-V supply. Each receiver converts TIA/EIA-232-F inputs to 5-V TTL/CMOS levels.
These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs.
Each driver converts TTL/CMOS input levels into TIA/EIA-232-F levels. The driver, receiver, and
voltage-generator functions are available as cells in the Texas Instruments LinASIC library.
The Thevenin equivalent circuit of this battery is 1.5V and 0.6 ohms in series. A more exact answer cannot be given without knowing the actual resistance of the 2 meters (I assumed infinite for the voltmeter and zero for the ammeter, as would be for ideal meters).
However I would NEVER attempt this test as you describe it, many types of batteries will explode like bombs when shorted (as they would be when an ammeter was placed across them)! The correct way to do this test safely is with just a voltmeter and an adjustable high wattage resistor.
Why do you need to use a static mat and a wrist strap?
To prevent electrostatic discharge to crucial components regarding the electrical circuit you are performing work on.
Describe the difference of V and Ah in a battery?
V is the batteries rated voltage. Ah is the amp-hour of the battery. This is a rating of how many amps it can supply for a given period of time. For example a 600 Ah battery with a 100 A load means that the battery should last 6 hours.
Is there a Rw to dB conversion chart?
Rw is measured in units of dB, there is no need for conversion.
What is the input and output voltage range of ic7408?
A: The answer deviate from IC to ic . It is defined not as voltage but rather as unit loads. In other words there is a limit to how many inputs can be tied together along with how many units can be driven for reliable operation. So basically is a question of current sink and source for both input and output which strictly relates to reliable triggering voltage levels. If I remember i used the 8 for unit load for the input and 40 unit load for the output. These numbers are general use for design.
Can any analog signal be converted to digital?
yes of course we can convert an analog signal to digital...
the device which converts analog to digital is called ADC{ANALOD TO DIGITAL CONVERTER}..
AND IT USES A VERY SIMPLE TECHNIQUE
i will tell you how.
let us suppose we are having any analog signal,
so we find the maximum amplitude of that signal by looking at the curve.
then we find the minimum amplitude of that signal.
thus we are now having the full range of the signal between which its value remains..
now let the maximum value is 5 volts and minimum is 0 volts.
so what we do now is that we take any reference point between 0 and 5 volt
let us split 0 -5 volt in two groups
1)0 to 2.5 volt and
2)2.5 to 5 volt
now by the help of programming we set 0 to 2.5 volt as zero and 2.5 votl to 5 volt as 1
so what ever value which will lie between 0 and 0.5 will be converted to 0 and the values between 2.5 and 5 will be converted to 1.
thus we get a digital signal from an analog signal
