What is circuit diagram for AB plus AB?
Is your question from digital electronics if yes than, AB + AB = AB ;and we can get this by using an 2 input AND gate(7408) where the two inputs are A & B and output will be AB.
Only valid in digital domain.
Why wouldn't a SHARP yo-p20hii be working?
The SHARP yo-p20hii is not working because its cells are down.
Which one has the ability to destroy entire cities and impair electronic communications systems?

What is the meaning of 1 and 0 in digital electronics?
In digital electronics "1" generally means on," 0 " means off. This simple system is the basis of all electronics that male up computers and the uses of digital signal analysis. All the data in computers can be broken down to one and zero.
Hi, DV cable is nothing but "Digital Video" cable and is used for connections with computers, DVD player and video camera/camcorders. It is also called as a firewire cable. It look like a USB cable which you can find on many computers and electronics gadgets.
Hope this helps,

Purpose of temperature sensor in Nicad type battery?
The temperature sensor provides feedback to the charger to allow the charger to determine when the battery is fully charged. The battery under charge develops internal heat as it approaches full charge. The temperature sensor measures the heat (temperature) and reports it back to the charger to end the charging cycle.
How do you use the tone function on your Arduino?
The TONE function on the Arduino generates a square wave on the specified pin based on the parameters specified. In other words, it quickly turns the pin on and off at the frequency specified. The syntax is:
Tone(p,f,d)
where p = the pin, f = the frequency in hertz (number of times per second) and d = duration to sound the tone in milliseconds (thousandths of a second). So, if you want to play the note middle C (about 260 hertz) for two seconds on pin 3 you would call:
Tone(3,260,2000)
In terms of hardware, you would need to connect a small speaker to the Arduino pin, one connection to the output pin (3 in our example) and the other speaker connection to ground (GND).
What do electronic designers consider when designing a product?
They consider these facts and design the circuit according to their result.
1>Input
2>Processing
3>feedback (for controlling output)
4> component to be used.
5> Effect on the circuit from non electrical quantity like heat pressure and effect on output.
6> reliability.
7> operating speed
8> coast
9> output
10> distortion
and some others facts which are considerable under design procedure.

How to fix Dell Laptop it accepts password and allows login but the desktop appears blank white?
Restore it to factory default
When you restore the computer to the default factory configuration, all data on the C drive is deleted. Before performing this procedure, back up any personal files. If you do not back up these files, the data will be lost.- 1. Restart the computer
- To do this, click Start, click the arrow next to the Lock button, and then click Restart.
- 2. As the computer restarts, press the F8 key until the Advanced Boot Options menu appears on the screen.
- Note: You must press F8 before the Windows logo appears on the screen. If you press F8 after the Windows logo appears, the Advanced Boot Options menu does not appear on the screen. If you do not see the Advanced Boot Options menu, restart the computer, and then repeat this step until you see the menu on the screen.
- 3. Press the Down arrow to select Repair Your Computer on the Advanced Boot Options menu, and then press Enter.
If thi
- 4. Specify the language settings that you want, and then click Next.
- 5. Log in as a user who has administrative privileges and
click OK.
- 6. Click Dell Factory Image Restore.
- 7. In the Dell Factory Image Restore window, click Next.
- 8. Check the box saying Yes, reformat the hard drive and restore system software to factory conditions.
- 9. Click Next. The computer is restored to the default factory configuration.
- 10. When the restore operation is completed, click Finish to restart the computer.
If this process does not work take it to a computer Repair man. Look for a computer store around your home and they could most likely fix it.
How much does an electronic inventor earn on average?
Very little, it's a hard life. Most "inventions" do not make any money, but cost a lot to get patented.
Where can one find a free online course in basic electronics?
"Electronics Theory" offers an online basic course for free. Open Culture also offers free courses on electronics and on other subjects from universities around the world.
Difference between transformer and induction motor?
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link.
2. Induction Motor has high no-load current than transformer.
3. Induction Motor is a dynamic device.
4. Induction Motor has high power factor.
What type of light has a longer wave length ultra violent or infrared?
Ultraviolet has the longer wave length
Infrared has the lower wave length
What types of products does Marantz electronics produce?
"Marantz is a company that sells audio products. They are primarily mid to high range in quality and the types of products include Compact disc players, handheld MP3 players and stereo tuners."
How capacitor introduces phase difference of 90 between voltage and current?
When you turn on a switch between a battery and capacitor, there is an inrush of current, but we measure zero volts across the cap because it is effectively shorted at this instant. As the cap charges, current drops and voltage rises. When it's fully charged, the voltage is max, and no more current flows.
If we put AC across the cap, it does this every half cycle. Max, current, zero volts, building up to max voltage, zero current. Then it does this for the other half cycle.
If we plot this on a graph, the voltage goes from zero to max at the same time current goes from max to zero. We say that "The voltage lags the current". Do this over several cycles and you'll have a sine wave for voltage and cosine wave for current. Sine and cosine are 90 degrees out of phase.

What is the difference between 60 htz and 120 htz?
the difference between 60Hz and 120 Hz is that.
60 hz wave will have wavelength of 0.016667 meter and change positive negative cycles 60 times in one second .
while in 120Hz wave it can change positive and negative half cycles 120 times in a second and also has wavelength 8.333 mm
Proper electrode placement for Holter monitoring is?
According to ACC guidelines:
2 channel monitor (5 lead wires)
White: 1st intercostal space, mid-clavicular on right
Black: 1st intercostal space, mid-clavicular on left
Green: Lower right at the last rib, just anterior of the mid-axilary line (ground lead)
Brown: 4th intercostal space, right sternal border
Red: Lower left at the last rib, just anterior of the mid-axilary line
I have never seen Holter leads placed as described below, but you should check with your Holter manufacturer guidelines.

**********************************************************
Green = left clavicle
Red = top of sternum
White = on the right side of the sternum, 4th intercostal space
Brown = middle of sternum
Black = left side of the sternum, 4th intercostal space
I think that's it at least.
Is it safe to take apart electronics if they are unplugged?
In most cases it would be safe. but some devices such as TV's and CRT Monitors can hold voltage for an extended amount of time. be sure to do some research on what ever it is your tinkering with before opening it. Also, electronics with large value capacitors either electrolytic and "oil can" capacitors can hold a significant charge until discharged. Always discharge all capacitors before touching any part of the circuit.
