Does a VCR have a magnet?

A VCR (Video Cassette Recorder) uses electromagnets in the record, playback, and erase heads. An erase head can also have a permanent magnet in it.

What are the pros and cons of electronic publishing?

The pros of electronic publishing are open access, rapid publication, lower costs, high visibility and international readership. Cons are a perceived lack of credibility compared with paper publications. They also do not have an adequate peer review process.

What is the meaning of Fuse Card?

The wire used to repair rewirable fuses comes wrapped around a piece of cardboard with maybe 3 different fusible rating wires on it, is this what you mean?

What is the maximum voltage that the VOM can measure?

Mine can measure 1000 volts. After that special insulated test leads are needed to protect the operator.

What is the Importance of characteristics impedence of co axial cable at high frequency?

The characteristic impedance is rather important. Input and output equipment connected with co-axial cable should all be at the same impedance for efficient power transformation and a clean wave shape. All co-axial cables have a characteristic impedance due to their physical dimensions. The main contributor is the distance from the center conductor to the braid. This is mainly capacitance and stays constant. As the frequency goes higher across this capacitance; the effective impedance seems to decrease. As the impedance to the braid decreases; less power gets to the output end of the cable. Even worse, the wave shape gets distorted. Even a digital signal rounds off and looks like it is leaning. Impedance is rated at a particular frequency band.

How does a voltage divider work?

The essential circuit of a voltage divider, also called a potential divider, is:

Why fet are used in linear ic?

fets are used in linier ic's to

1)to provide large resistences

2)increase input resistence

Why does the Nokia N97 Mini say the headset is plugged in when it isn't and wont play music through either the headset or the music speakers?

Ive fixed it now.

By throwing it at the wall when i was angry.

No im not joking...

this phone is really confusing so I wish you guys luck with figuring it out!

Full form of BIT?

binary integer

don't think so... It's binary digit.

Can inserting a resistor in a circuit have an effect similar to an open circuit?

If the resistance is large enough, then there might not be enough voltage difference to allow much current. Since, Voltage = Current * Resistance, if resistance goes really large, and your voltage doesn't change, your current must decrease. An open circuit is where you do not have any current flowing, so whether no current verses very little current is the same is up to you.

What kind of energy does a stun gun have?

A stun gun has two numbers associated with it's power. The first is amps. Stun guns run about 3-4 milliamps. A full amp will kill someone and AED's run as high as 500. So a stun gun won't even mess up a pacemaker, much less cause arrhythmia or death. The second number is voltage. This is the number you see plastered across ads for stun guns. It really doesn't have much to do with the stopping power or a stun gun, but the higher voltage guns do work quicker and might possibly work better through thicker clothes.

What wattage of inverter would you need to power a 100-240volt 1.7 amp laptop?

At 100 volts, around 170 watts. At 240 volts, around half as much. So, I'd suggest a nice 200 watt inverter for the 120 volt model, but that seems to be an awful lot for your purposes. Are you sure that you're not reading the power output of the power adapter, as compared to the amperage it draws on A.C.? I seem to remember using my laptop in a truck with just a 40 watt inverter and it worked just fine.

Do most electronics run on both 220V and 110 Volts?

Most electronic equipment runs on far less that both of these voltages. Most likely from 5 to 12 volts DC. To get down to these votages it has to be processed by a transformer. Good equipment will have a switch on it so that you can chose what the input voltage will be. All this switch is doing is changing the taps on the primary side of the control transformer. The secondary side of the transformer is the working voltage of the equipment 5 to 12 volts. The secondary side of the transformer is then put through a full wave bridge rectifier to change it to DC. When you charge your cell phone this is all that you are doing when you plug it into the wall, except without the switch to select the 240 volts. The rectifier is built right into the wall PAC and out comes the voltage your cell phone is looking for.

This planet is usually running 120 ac or 220 AC That is what most of the people knows as power. There is and never will be a set of voltages that will run everything. but there are some industry standards personal computer are 3v,5v,12v ,12v. these voltages are not are set but are carefully chosen for efficiency a room heater will take forever to heat a room at 5v. so the conclusion is voltages are chosen for efficiency and nothing more then that.

How long is the average 60-minute audio cassette tape?

Answer

The easy answer is 60 minutes, but you probably meant length in linear inches. Cassette tapes run at 1-7/8 (1.875) inches per second.

A C60 plays 30 minutes on each side, and requires 3,375 inches, or 281.25 feet of tape. Most manufacturers round it up to 285 feet, so the result is approximately 31 minutes per side.

Is sacd or DVD-audio dead Are manufactures still producing booth types of formats?

SACD is not dead. It is however a niche format. There are plenty of new releases - majority of which is classical music. High definition format such as SACD really only benefits quality recordings of music with high dynamic range such as classical and jazz. Likewise, there are SACD players that are still maufactured - most notably the Sony's PlayStation 3 (some models only) and also various models from Marantz and Denon as well as cheaper Oppo. DVD-A does appear to be dead to my knowledge.

Who first invented the VCR?

VCR stands for Video Cassette recorder. The invention of VCR was initiated by the invention of Audio Cassette players. The first type of VCR was the U-matic that was developed by Sony Japan during 1970. The home VCR system that we see now were developed by Philips in 1972. Since large organizations like Philips and Sony work in research teams. It is difficult to tell one name that invented the VCR as it was a collaborative effort of the team working on it.
