How do you connect a Compaq laptop to a Technics stereo system to listen to the music stored on the Windows media player through a surround sound system?

Your laptop should have a plug for a stereo miniature phone jack, which is the same type used for stereo headphones. A patch cable which has this type of plug at one end, and a pair of RCA plugs at the other is widely available. By pluging the miniature phone jack into the laptop, and the RCA plugs into the input jacks of the stereo, you should be able to listen to the laptop over the stereo. This solution works, but the sound output through the headphone jack for most laptops is equalized for headphones. It is heavy on the base and light on higher frequencies. It will not be satisfactory for many people.

What are the of the camera?

A lens, viewfinder, and shutter are the main parts of a camera. If it is a digital camera it will have more parts than a manual camera.

What is the relationship with leakage current and rated voltage of high voltage surge arrester?

Not much actually; Electrons escaping through insulating material is defined as leakage current. Insulation has both resistsance and capacitance abilities, which means current can flow through both paths. Given the nature of current it will find the quickest path. A surge arrestor dissipates (discharges) voltage spikes through a series of resistors and diodes. A surge arrestor is commanly used in applications above 100kv. Dnot confuse a surge arrestor with a surge protector, whch is basically a circuit breaker. FIRST OF ALL THERE IS NO PERFECT INSULATOR AND ELECTRONS DO NOT ESCAPE BUT THE EMF IF HI ENOUGH WILL FIND A PATH TO BLEACH ELECTRONS BECAUSE OF DIRT MOISTER WHATEVER.

What is the functions of led flashlight?

same as any other flashlight, So you can see better in the dark. Since the power consumption of LED is far roo less for the same lighting condition, battery life is more.

What is oscillatory discharge?

Alternating current of gradually decreasing amplitude which, under certain conditions, flows through a circuit containing inductance, capacitance, and resistance when a voltage is applied is known as Oscillatory discharge.

How do you record a video on an acer laptop?

Ok well first your going to need a webcam I'd suggest looking on:

Amazon.co.UK

eBay.co.UK

For any Webcams you need.

Once you've got the Webcam/Camara look through the box and find the Drivers CD (Which will be like the only CD in the Box, Once you've found it put it into the PC and install the drivers (Its just like any other installation) Once that's done plug your Webcam into the PC via a USB port and then open the Software you installed (when you installed the drivers it probebly came with Filming software to)

Now open that software and from there you should be able to find the Record button.

I've just had a look at Acer's website, If you've got one of the new laptops that come with webcams then you need to look through the box the laptop came with and find the Drivers for the Webcam, Install it and there we go, Should be simple from there.

Why does my reel to reel play low volume?

Dirty head? or could the tape be flipped over? It happens.

Non-ideal properties for op-amp.?

limited band width and very low amplification factor, to begin with hi voltage and current offset

How do you burn a CD to play in a regular CD player?

Use windows media player or winamp:

In widows media player click on the "Burn" tab then drag the songs over on to the side bar that popped up then hit burn.

In winamp select the songs by holding down the "ctrl" key and select the songs you want the right click on them and go to where it says "send to" and after it expands click "cd burner on E:" (or whatever your drive name is).
