How many amps does a cordless drill draw?

Full size drill can draw up to 20A. Depends on drill/battery/torque. You can wire inline fuse holder and step down fuse amperage until it blow. It won't be a peak but some averaged max current, see fuse characteristics.

Is it better if a wavelenght on a laser pointer is higher or lower?

The wavelength only reefers to the wave length of light in the visible light spectrum in. Basically what colour it will be. The Higher the number the deeper purple (violet) it will be. Too high it will be an ultra violet laser, which we can not see. The lower the number the deeper red it will be. Too low it will be infra-red, which we can not see with the naked eye as well.

The mW (milli-watts) is what determines if the laser is going to better. The Higher the mW, means the higher power output, which means, a brighter, better laser.

At any wavelength, and enough mW, all lasers are very dangerous. Ultra-violet and infra-red lasers burn and cause eye damage all the same as the visible light lasers.

Can you use a 9v 300ma ac adapter in 9v 100ma socket its for a micro guitar amp?

yes but the device will not work property or nor work at all

<<>>

No, the 100 mA adapter will be too small to operate a device that requires 300 mA for its operation. By trying to draw a higher current than the adapter can supply, the adapter will heat up and possibly burn itself open. In other words the adapter will stop working.

To set your skyscan hd-1688 atomic clock?

Take the battery out. Use a large paper clip to bridge the battery contact points (to ensure proper re-set). Then put in a fresh battery. The hands should autmatically move to the 12 O'Clock position. When the radio receiver in the clock registers the time broadcast from WWV it will display the correct time.

Alternatively, you can press the M SET button (above the DST switch) until the hands advance manualy to the correct time.

How do you use a Xerox machine?

A Xerox machine is any machine manufactured or markets by Xerox Corporation with the company brand on it. The company sells several different kinds of machines, so how you use one depends on what kind of machine it is.

The machine most commonly associated with the Xerox name among the general public is the photocopier. Several other companies make and sell photocopiers using their own brand names.

When using a photocopier, you generally just open the cover, put the sheet-to-copy on the glass table revealed by opening the cover, close the cover, and press the copy button. Most machines have other buttons for more advanced features, but those vary by machine.

If you have a 2007 old blu-ray bdp-s300 and The Day the Earth Stood Still takes 10 minutes to load and then won't play what is wrong?

What are rebuttals to advantages of nuclear power in a debate?

None really. It's clean, sustainable, even the spent uranium can be used in planes, tanks, and ammunition. I guess the only argument would be safety, unfortunately for you, the track record of opperational safety is quite excellent. One thing you could talk about is waste storage, but even that is becoming safer as technology advances

What is a palendromic number?

A palindromic number or numeral palindrome is a 'symmetrical' number like 16461, that remains the same when its digits are reversed. The term palindromic is derived from palindrome, which refers to a word like rotor that remains unchanged under reversal of its letters. The first palindromic numbers (in decimal) are:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, … (sequence A002113 in OEIS).

Palindromic numbers receive most attention in the realm of recreational mathematics. A typical problem asks for numbers that possess a certain property and are palindromic. For instance,

* the palindromic primes are 2, 3, 5, 7, 11, 101, 131, 151, … (A002385)

* the palindromic square numbers are 0, 1, 4, 9, 121, 484, 676, 10201, 12321, … (A002779).

I HAVE A crunch 1000.1 AMP THAT im trying to push 1 punch p3 15 subwoofer how do i wire it?

If youre running a single woofer get the dual 2 ohm woofer. Wire them parallel, which will bring it down to 1 ohm when you put it on the amp. 1 ohm will pull the most power from the amp

What are halogen headlights made with?

Tungsten filament

Quartz glass (needed because they are much hotter than ordinary bulds)

halogen gas to fill build (chlorine, fluorine, etc) or Xenon in newer types still caused halogen but they aren't really.

bright white light because filament can get hotter in halogen atmosphere than normal filament (also tungsten) can in normal bulb atmosphere (normally nitrogen)

Why CMOS is the most popular integrated circuit technology?

although very sensitive to static electricity, CMOS is very stable compared to other (older) technologies. it also can handle wider voltage ranges (standard 3.3volt to 18volt) upto 40volt in some cases. in addition CMOS requires very little current (amps) compared to other technologies (1/1000 of amps required for ttl) the static problem is overcome with good handling practices (always earth your hand and handling equipment to each other)

What guitar effect mimics other instrument exsample playing an electric guitar using an effect to produce a piano like sound?

AnswerGuitars by themselves can't play sampled sounds since they use magnetic pickups to capture the vibrating strings. However, guitars can be fitted with special pickups that convert the analog sound of the string into MIDI information. Once this conversion is complete, the guitar can trigger any sampled sound imaginable.

Some newer guitars use this technology of conversion to build different sounds directly into them. E.g. a Fender Stratocaster can sound like a Les Paul or a Martin Acoustic or even a banjo.

AnswerA piano would be hard for an electric guitar to emulate because of its tonality. However, I have gotten sounds close to church bells or organs using an Electro-Harmonix Polyphonic Octave Generator (POG). Heavy chorusing can turn a guitar's natural sound into something else.

In addition, take your' guitar out to the shops and plug it in and play. What you are describing could mean almost anything to the people on this site. You know what your' looking for.

Is ham radio and shortwave the same?

Not necessarily. Normally, Ham Radio is used to describe amateur, 2 way radio where 2 individuals talk to each other back and forth; on the other hand, shortwave radio generally is used to describe commercial High Frequency radio broadcasting. This band is a commercial service that provides long range (worldwide) audiences for broadcasts but is a 1 way media. Think about a local FM radio show that you could listen to anywhere in the world but you can not talk back to them.

How many volts does a kettle take to boil?

It is not dependant on voltage.

Kettles are made in various voltages. 240v in the UK, 110v in the USA and they even make 12v kettles for vehicles.

The amount of work required to boil a kettle is measured in KiloWatt/ Hours.

This value will vary depending on the amount of water in the kettle and the efficiency.
