How does one set a digital projection alarm clock?
Setting a digital projection alarm clock is best (most easily) done by referring to the owner's manual supplied with the unit. If it is unavailable, go to the manufacturer's web site and look under their customer support offerings or another "appropriate" heading to see if the owners manual can be viewed online. If any are still being sold in nearby stores, get over there and see if a demo unit (a unit that is open) has an owner's manual you can look at. Or, you could experiment. (It is noted that the make and model of the unit were not supplied. That limits the amount of help that can be offered.) Failing that, go to the source. Contacting the maufacturer is relatively easy. All the big one's have 1-800 support and email. Good luck.
How do you use a multimeter tester on dryer coils?
Generally, dryer coils either work or they don't. A multimeter can help you determine if a dryer coil is "burned out". If the coil has "continuity", it's probably fine. Generally, if there is a hot spot in the coil it will burn out rapidly.
What is a common mode amplifier?
I'm not sure there is such a thing as a "common mode amplifier". The common mode rejection ratio (CMRR) of a differential amplifier is very high, and is defined as the ratio of the differential amplification divided by the common mode amplification. The common mode amplification is what you get when both inputs are tied to the same signal. Ideally, this amplification will be zero, but in reality it ends up being some very small amount for well designed amplifiers.
This is a beneficial trait for audio equipment which use a positive, negative, and neutral connection (balanced cables, such as microphones). Noise signals will naturally couple to these cables. The assumption is these noise signals will couple nearly identically to both the positive and negative signal wires, so when applied to the amplifier, this common mode signal will not be amplified, while the desired signal (which is created so that the positive and negative signals are opposites) is amplified.
How do you detect location of caller?
Are you looking to detect the location of a caller on a cell phone or a land line phone? If you have the area code or country code you could search that number for starters.
Did you know that anyone can fake their caller ID number making it seem as if they are calling from anywhere they want? You should never rely on what the caller ID says for determining a callers location......for your own safety.
What is the legal power limit that ham radio operators must follow?
There are three classifications (Technician, General, and Extra) of ham radio operators. Depending upon the band or frequency they are operating on and license class, some bands only allow 25 to 100 watts of power. The maximum power that a ham can operate with is 1500 watts. This is controlled by the FCC. The FCC website has all the information about which bands and licenses are necessary.

How do you set or turn off DST on a Skyscan 38229-1?
SKYSCAN ATOMIC CLOCK model 38229-1
Clock may not reset automatically when after 'SPRING FORWARD' or 'FALL BACK' time changes.
How to Reset:
Unbend large paper clip and gently insert tip into 'RESET' hole on back of clock for two seconds. Then:
1. press "MODE" (it will show the alarm time)
2. press "ADJUST" (this will switch the time zone from PST to EST)
3. when it is on the desired time zone, press "MODE" to return to the clock.
Now place clock near window where southern exposure allows access to satellite. Icon for satellite access should activate (looks like a dish satellite). Allow several minutes for reset.

after a couple weeks/days the ipod finally shuts down and restores which means basically everything is restarted on that device
How do you switch the locked out channels on a regency scanner Z 10?
Simply press the SCAN button to put the scanner in scanning mode, then press the number button for the channel you want to lockout or unlock. For example, to lockout channel 5, just press the "5" button while scanning; to unlock channel 5, press "5" again. This works for many Regency scanner models.
Does potential energy increases or decreases when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
How do you hook up a 1 farad capacitor to your amp?
The key is lots of capacitance, as close to the amp as possible, and thick cables capable of carrying lots of current.
Answer 3Be very careful with that thing. The current output of a capacitor is the product of capacitance, in this case 1, and the change in voltage with time. Thus, if you do something to cause a quick change in voltage with that, you will get a very large current spike, possibly hundreds or even thousands of amps.Also note for this reason you should really pre charge capacitors of this size. Let's say you have 1 ought wire run from your battery to the cap, with a resistance of .001 ohms. (I actually have no idea what the resistance of your wire is, I just made that up for argument's sake) When you connect the discharged capacitor, you are causing an instantaneous change in voltage. (IE dv/dt equals infinity) This means that the capacitor will appear to the circuit as a dead short. Thus, the _only_ thing limiting your current flow is the wire. Ohm's law states V equals IR. As the wire is only 0.001 ohms and the system is 12V, this means that when you connect that cap to your car battery it will ["try to"-j3h] draw 12000 amps. I don't think that's good for any part of your system.
The solution? Get a resistor and charge the cap through it. The resistor will limit the current flowing into the capacitor until it is fully charged. Then it is safe to connect as the potential between the capacitor and the battery will be 0VDC. A light bulb will work very well for this task, if you don't have any power resistors laying around. This will lengthen the life of both your battery and your capacitor. Also note that if you have a fuse between the battery and the cap, the surge current will blow the fuse without pre charging. If you have a switch or relay in between the cap and the battery, a pre charge circuit must be used as the surge current will weld the contacts closed. (I've seen it)
Answer 4Hi -Don't mind me but fortunately a car battery really can't put out 12,000 amps due to the limiting source impedance of the battery- You might get only a thousand amps at best !!!!(using thevian and norton theory)-OK this is still dangerous. OK like a lot dangerous but the internal resistance of the source, the battery its self is also a part of the equation- Dead shorting a battery is bad news- also you might consider the time constant to charge the cap !!! Tc= R times C (five usually required for full charge)
Answer 5
In each "Time constant" (T) the potential on the capacitor will increase .67 of the remaining way to the battery potential. If the limiting resister is large, this could take minutes, if small then milliseconds. You want a few seconds.
Yeah LIKE anybody can go out and buy one. 1 farad is very big to charge that thing, it will take forever if and one volt supplied from a one ohms source and 1 ohm 1 x 1 x 5 = 5 seconds. Now it is almost fully charged. Some people just don't pay attention to what they read I guess. How to connect it to the input a very Good short for a very long time at the output the same results
Answer 6
First of all I'm going to say all you have to do is make sure that you use thick oxygen free car audio wire. I did a reinstall the other day and someone had used 220v household cable to wire their amp! Who does that? that being said single -aught is going to be efficient enough for all of you 1 farad guys it's easy just make sure pos to pos and neg to neg and for goodness sake charge the thing before you use it. If you read up on this page somebody has already taken the time to explain the ohms law and how to blow up your battery so be careful.
Answer if it is a capacitor made for a car amp the have a circuit board on top so they will not instantly charge off the battery they will charge slowly till they are full on their own that's how they were designed.
Re; Answer 6. What on earth is "oxygen-free audio wire"? I have assembled a good deal of industrial electrical and electronic equipment over the years, much of it to tight quality-control specifications, and NEVER has that description appeared anywhere. And this is equipment needing better quality than in a hi-fi. Those peddling it have found a nifty way to charge over the odds for... plain, or perhaps tinned, copper wire. Yes, some copper is treated to remove any included oxygen but that is for heavy sheet and profile sections purely for welding, to prevent brittle welds: its electrical properties are not affected. It matters in some parts of an audio circuit that the leads are screened against interference, and the wire should be bright or tinned in connections because surface oxide will degrade the connection and may even introduce odd partial-rectification problems, but the notion that it has to be some magical "oxygen-free audio wire" is a myth and a con.
Careful not to exceed the Caps voltage rating. 1 farad caps typically are a low voltage device.
