Electronics Engineering

Joules is equivalent to power over time. Power is equivalent to volts times current, so your question does not provide enough information to answer.

To look at another way - you might ask how many joules (a measure of energy like kWh - what your electric company bills you on) are in 120 volts. If this were not dependent on current, then you would be constantly billed for every outlet in your home, regardless of whether they are in use. The fact that 120 volts is present at all outlets at all times does not mean that power is being used at all times.

Stabity factor is not a circuit.It is a parameter,which decides the ability of Biasing circuits,to keep the Q-pt stable in the center of DCLoadLINE.It should be as low as possible

A: The gain of a transistor is not linear and even that varies from component to component. The gain can vary greatly depending on the Ic current and the load. Manufactures only give out a typical gain for a particular current. As a rule the lower the Ic current the higher the gain. To really find out what a particular transistor characteristics are a tektronik curve tracer is used.

A: THYRISTOR can be used to clamp damaging energy as opposed to a fuse that must blow open and invariably takes time to blow. A thyristor is much faster and controllable actually if the problem disappear it can be made to open up again and restore power for normal operation.

A: There are so Manny IC that is best if you learn how to research on your own at datasheetlocator,com

Internal friction created because the electrons hit the various metal's latices or atoms.

Higher the temperature more movements so the possibility of hitting is higher so more resistance to flow

Power factor does not apply to a resistive circuit. Just the current will follow the voltage (in phase)

A: There are LEDS of all kinds Each are designed for all kinds of purposed with all kinds of angles. power of emission and colors. Data sheets are manufacture specifications for each part that he sells and engineering take those sheets and choose for their applications. YOU may find data at datasheetlocator.com

A special semiconductor material is used in Light Emitting Diodes (LED). When an LED is forward biased, the anode is connected to positive and cathode is connected to negative terminal of the supply, then current flows through the LED, just like in a regular diode.

The electrons in the special semiconductor are excited, and when they return to 'normal' state, they give off energy in the form of photons (light rays). One such semiconductor material which is commonly used is gallium arsenide.

Note: the photons are not necessarily in the visible light spectrum. The remote control for your television set or DVD player most likely has an infrared LED, to transmit information to the TV.

Ohm's Law: V = I*R, so Voltage and Current are directly proportional and a change in voltage will result in a proportional change in current. (The current reduces by the same factor)

Worldwide regulation always uses FDM for separating different systems (TV, WLAN, radio, satellite …). Thus, all radio systems must modulate the digital signal onto a carrier frequency using analogue modulation. The most prominent system is the traditional radio: all music and voice use frequencies between, e.g., 10 Hz and 22 kHz. However, many different radio stations want to transmit at the same time.

Therefore, all the original signals (which use the same frequency range) must be modulated onto different carrier frequencies. Other motivations for digital modulation are antenna and medium characteristics. Important characteristics for digital modulation are spectral efficiency, power efficiency and robustness. Typical schemes are ASK, PSK, FSK.

It is an inverting comparator with a positive feedback, can convert an irregular shaped waveform to square waveform. it is also known as squaring circuit.

A: class a

yes,obviously its good to have high bandwidth....according to technical feild

All a.c. voltages are expressed in root-mean-square (r.m.s.) values, unless otherwise stipulated. So 12 V is an r.m.s value which, for a sinusoidal waveform, has an amplitude, or peak value, of 1.414 x 12 = 16.97 V. So its peak-to-peak value will be twice this amount -i.e. 33.94 V.

A: Actually no. If the current can be limited it may Even oscillate and each diode will behave differently even tough they are from the same family. A reverse breakdown usually means a blown diode in a circuit the hear from a hi voltage and the hi current will surpass its power dissipation and blow short most of the time.

According to the EIA-96 system which applies to SMD resistors, it means 10K (10,000 ohm), 5% tolerance.

first of all we have to know that about band,so band is range of frequency which we have selected for example:we have a low pas filter it frequency always started from initial or 0 HZ upto cutoff frequency and here remember that cutoff frequency we will have to select after cutoff signal is rapidly down now about band rate so your signal is band at certain rate is called band rate.

The current should be high enough to maintain the voltage at each division. Generally, the current should be ten times the load current or the voltage will be across the voltage divider.

If possible use regulators or zeners or regular diodes. I'm not saying dividers are bad but there are less current sensitive solutions.

It's a misleading term used to market knives (or razors or whatever). There is no process where knives are actually sharpened by lasers. But I believe some manufacturers measure an edge's angle using a laser either while sharpening or afterwords in quality control. It is debatable whether this helps the process in any significant way (a good sharpener doesn't need a laser) or whether it's only done so that the manufacturer can make misleading claims about their 'laser sharpening.'

Doug cooper is a tool

It depends if the are in series or parallel.

In series: 55K ohms

In parallel: 5K ohms

It really all depends brah.

This is bcoz we need -48V for Gsm BTS, -48 DC is used to control Fluctuation

So the main function of this is

1) To convert AC to DC

2) To control overloading
