Active and passive components?

Electronic components are divided into active and passive categories. Passive components are those that do not exhibit gain or directional characteristics. They include resistors, capacitors and inductors.

Active components are those that show a gain, such as a voltage or current gain, or have a directional characteristic such as a diode conducting only in one direction. Transistors, diodes, triacs and SCRs are examples.

There is something of a debate about certain other components. Transformers, motors and relays are sometimes called active and sometimes not. It is perhaps more important that their function is understood than how they are classified.

How does a telephone use electromagnets?

The crank on it formed a generator and the field in the bell coil made it ring.

What is the function of an LDR or a TDR in an circuit?

The function of an LDR or light dependent resistor is to change the brightness of the light based weather conditions or light hitting the object the LDR is on. When it is darker out, the light does not shine as brightly.

I also have the Orange and Yellow ones that you must put in the correct places. They are on the same row and there is one gap between the two. After I placed these I did the orange ones, then moved to the yellow as I was down to 5 instead of 6. I am sure you can put the rest of the colors on in any order but try to stay with one color group at a time, also I noticed that most of the colors came out to be running diagonally. Finally, the row on my board is the 3rd one down from the top (there can 4 tops but you'll find it) each time you start a new color start it on that same row, I have practiced this twice now and the second time around I did it in about 15 minutes. To find out which orange and yellow to use just look at the bottoms of them before and you will see the difference. Again, I am not sure if it is just the orange and yellow ones for everyone else but based on the production of the game and the other post I would assume confidently that this was the way the game was built. Pretty tricky ThinkFun...

My mother got a copy of this for Christmas, and I have to say that I'm in awe of the deviousness of Thinkfun, Inc. If you follow the implicit "rules" of the game - placing height-6 towers on the shortest bases, height-5 on the next-shortest, and so on - there is no solution. This is a classic mathematical problem first called the "36 officers problem."

Thinkfun got around this through a trick. One of the height-6 towers and one of the height-5 towers are manufactured slightly differently from the other five. (In my mother's version, these were orange and yellow respectively. I don't know whether this is constant from unit to unit, though.) The base is also constructed so that one of the shortest bases is slightly wider than the rest, and one of the next-shortest bases is slightly narrower. This means that you can put one specific height-6 tower on what would normally be a height-5 base, and vice versa.

Once you've placed these two towers in their swapped locations, the rest is trial & error.

How to solve the 36 cube.

First find the 6 piece and the 5 piece that are different (slightly) look inside at the middle.

On mine it is orange 6 and yellow 5.

Now orient the cube up. To find up the 3rd row has the 3rd position and the 5th position interchangeable with the key pieces you found. This 3rd row is your key!

The 6 orange goes in the 3rd position and the yellow goes in the 5th position.

Now fill in the orange with the diagonal toward the lower right corner using 3 oranges total.

The bottom row has the orange in the left corner. Row 1 has orange in the position 2. Row 2 has orange in position 6. Orange is done.

The yellow Key 5 is in the 5th position. Going on a diagonal toward the lower right corner add the yellow in the 4th row 6th position.. From the upper left corner going on a diagonal now meet up with the orange partial row.

The row 5 has yellow in position 3 and the row 6 has the yellow in position 4.

Yellow and orange should be done.

Starting in position 4 in row 1 go diagonal to row 4 position 1 with the color of your choice.

Now at row 5 position 6 and row 6 position 5. Fill in the blocks. The puzzle is ½ done.

Now starting in your key row 3 position 4 go on a diagonal to upper right corner with a color of you choice

Row 5 position 1 ,and row 4 position 2. Finish off that color with row six position 3. 2/3 done

The other 2 colors have random pattern.

Row 1 position 5, row 2 position 1, row 3 position 6, row 4 position 3, row 5 position 4, row 6 position 2.

Put the remaining where they fit.

Done.

After memorizing the pattern you can solve in less than 5 minutes.

How To Fix Scrached Up Wii Games?

Get a CD cleaner or go to a CD cleaning place. You could also bring the game to the place you got it or nearest vidio ame store, depends on the damage done.
If the scratch is really bad I have had success with car scratch remover followed by car polish. Use a clean damp cloth and apply the scratch compound from the center outwards until the scratch fades ( you will have to wipe off the haze to check). After this is done just apply polish in the same manner and then buff it off with a clean dry cloth. This worked to repair an unreadable Mario Galaxy disc for me when all the other suggestions failed.

What are everyday uses of series circuits?

Your battery-powered flashlight is a good example of a DC series circuit. Battery power is DC. The battery is connected to a wire or piece of metal that's connected to a switch that is connected to an incandescent light bulb (resistor/thermistor) which is then connected to another piece of metal or wire which is connected to usually a spring in the end of the flashlight which creates a ground to the negative terminal of the battery.

How many songs can fit on a 80 GB?

The number of songs that will fit in 80 gigabytes is dependent on the bitrate of the music being stored. Using AAC format at 128 Kbps, it is estimated about 19,000 songs will fit in 80 gigabytes.

How can you charge 6 volt dry cell?

If it is not rechargeable DO NOT attempt to recharge it, the battery can explode causing damage to you, your charger, to anything or anyone around ground zero.

If it is rechargeable you should have or you can get the proper charger.

Do Not just get any charger It Must Be the correct Voltage and Amperage for your battery.

How and what does the telephone do?

Telephone cable wire is used as the medium for internet connection. With the incorporation of the internet and the telephone technologies, we can now conveniently and cost effectively exchange audio and video information.

A battery consists of five dry cells connected in series if the voltage developed by the battery is?

Approximately 7.5 volts, under no-load conditions, assuming that each cell is exactly at 1.5 volts each (which I assure you, it doesn't really happen that way in the real world, but it's close enough).
When cells are connected in series, the voltage is the sum of all individual voltages. In this case, with 5 cells in series (each at 1.5V), the total voltage would be 1.5V*5 = 7.5V

Difference between tig and mig?

It depends on what you're welding and what kind of weld you need.

For an extremely strong weld where you don't want to transfer as much heat to the surrounding areas, tig is the way to go. Tig has the option of melting only the source material (together), so if it is better than no material is added, then tig is the better process. If you want a small, uniform weld, then tig is also superior.

Mig is wire-feed and so adds material to the pieces being welded. So it is better for filling areas or adding superior strength. If the material surrounding the weld can take the heat or doesn't matter if it is deformed or discolored, then mig welding is the way to go.

A good discussion of Tig and Mig welding is here http://www.ridgecrest.ca.us/~biesiade/weld.htm.

Is Luigi In Super Mario 64 DS?

Luigi is not in Super Mario 64. But he is in Super Mario 64 DS. It is possible to play as Luigi in SM64 if you have the game on a computer with Project 64.Here is a gameshark code for Luigi(he wont have a L on his cap, but his colors and size) This can also be done on a real N64 with a real Gmaeshark 3.3 or higher to use the codes if not on Project64.

Can a stun gun knock you out?

think so if its set at its top level of power

ANOTHER VIEW:

If you use a 5.5 Million volts stun gun, the following will happen:

Touching someone with a 5.5 million volt stun gun, for less than a second, causes muscle contractions. Stunning an attacker for 5 seconds will cause mental confusion, loss of balance and loss of muscle control, leaving the person in a complete daze. Even if you simply fire it up in the air, it will make people stay away from you!

If the stun gun is weaker, you can get the same results if you touch them for a longer period of time.

How does a nuclear power plant generate electricity?

Basically, radioactive fuel, such as uranium is loaded into a reactor. Heat is generated by atoms splitting apart and generating heat energy; a chain reaction causes other atoms to split and generate more heat. Control rods are used to control the speed of the reaction. Water collects the heat energy and releases it to cooler water in a heat exchanger. The water is turned into steam, which turns a turbine that is connected to an electricity generator. The generator produces electricity which provides energy for homes, business, etc.

Where is the serial number on a blue mic yeti?

I recently bought 2 Yeti Mics to be used for podcasting. Unfortunately all yeti mics posses the same serial number so my laptop cannot pic up both mics. In fact I need to send one in to the manufacturer in order to get the serial number of one of them changed. Is there a work around that I can do to change it myself? As you can probably tell I am not too eager to pay shipping and wait for weeks just so that I can use a product that I have already purchased. Any help would be greatly appreciated. Thanks

Can you run 220 volt appliances off a 380 volt supply?

you could use a step down transformer if you had no other option. but the best thing to do is run a 220 feed directly from the fuse panel Step down transformers get very hot and do not last forever

What are the advantages of nuclear power plant to other power plant?

The main advantages of nuclear energy are the small amount of fuels can yield tremendous heat energies without emitting carbon. The problems of used fuel storage, radioactivity, and nuclear catastrophes seriously are the risks and to nuclear energy.

How do you connect two twelve volt batteries for my motor home?

You will want to connect them in "parallel" (positive to positive, negative to negative). If you connect them in "series" (positive to negative) you will add one voltage to the other, making 24 volts.

Who are the Filipino scientist who invented about electricity?

The Filipino electrician Agapito Flores is credited with inventing the fluorescent lamp independently of researchers in Europe and North America.

Flores is noteworthy because his work was done in relative isolation rather than in collaboration with other researchers. However does not have primacy, as his work was publicized after that of physicist Arthur Compton who is usually cited as the first person to develop a commercially-viable fluorescent lamp.

The situation is similar to that of the controversy surrounding the invention of the incandescent lamp about a half-century earlier. Thomas Edison in the US and Joseph Swan in England both developed the incandescent bulb almost simultaneously but Edison gets the credit because he demonstrated his work first.

What level does aipom double hit?

aipom learns double hit at level 32. If you want it to evolve make sure you let it learn double hit when it says aipom is trying to learn double hit. then level it up one more time for it to evolve into ambipom.

aipom basiclly evolves at level 33 just make sure it knows double hit
