A resistor is an electrical device that limits current in a circuit. It converts electrical energy into thermal energy (heat), and drops voltage. Conductors in an electrical circuit allow current to flow through them will little resistance. The medium in a resistor, the resistive material, is not a good conductor, and will "resist" the current that wants to flow through it. This is how it limits current in a circuit. A resistor is rated according to its resistance and it ability to dissipate heat. It will be rated in ohms of resistance and in watts. A one ohm resistor will allow one amp of current to flow through it when one volt is applied across it. It will generate one watt of thermal energy, which it will have to dissipate as heat.
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. Resistors can also be used to provide a specific voltage for an active device such as a transistor.

To prevent wire corrosion. Most phone wire is copper, and it is stripped and exposed to air at many points along its path from the telephone company central office to your phone. Also, breaks in insulation could expose small parts of it to water or soil. Any of these will allow the wire to corrode, and the usual methods of corrosion are that copper in the wire is converted to copper oxide or copper carbonate. Both of those happen as a chemical reaction where copper atoms act as positively charged ions to combine with negatively charged oxygen or carbonate ions in water or dirt. A wire with a positive charge will actually draw the negatively charged ions to the wire and will greatly accelerate corrosion. A negative charge will repel the corrosive ions and will slow the corrosion.

A negative charge will cause some copper to be lost due to a process called electro-deplating (reverse of electroplating), but the rate of copper loss is much less than would be caused by copper corrosion with a positive charge.

The phone company power supply acts like a giant battery. They ground the positive site of the supply so that any part of the system has a voltage that is zero or negative, so the whole system resists corrosion better and lasts longer.

A metal compound is held together by the attraction of the positive nuclei in each atom and the mobile electrons from the outer energy level of each atom. The fact that the electrons are free to move around the structure means that even if the structure changes shape there will still be an attraction between them and the positive nucleus of the atoms.

Short circuit is the case when electricity, instead of travel through the design circuit path, jump across an unintended low resistance path and bypass the design circuit.
A short circuit is a path for an electric current to travel through where there is very little resistance. This path is often, but not always, through a wire connected directly to a ground, and is often, but not always, unintentional.

- a mixture of gases is obtained

- at a given temperature and a given ratio gas1/gas2 an explosion is possible

if you use a uncharged capacitor most likely your car battery will drain much faster using a uncarged capaciter will mess up your amp good power source is needed for your amp to give its maximum potential for deeper bass and no dimming

A pressure switch would activate the compressor's motor starter. When the pressure drops below a set 'low' limit, the motor powering the compressor turns on, when the pressure reaches a set 'upper' limit, the unit turns off...How's that for "Straight Forward"?

Its the CR2032 battery

A Schmitt trigger is a comparitor circuit that is basically an on-off switch. It's either on or off (which we call high or low). Once a threshold at the input is exceeded, it turns on, or goes high. Below the threshold, it turns off, or goes low. Drive a Schmitt trigger with whatever you want. It responds in only two ways; high or low. It has no other output states.

== == As with most things, it simply comes down to money, and space. A larger PU resistor will guarantee a more solid output, but they cost more, take up more space, & waste more energy by creating more heat. So, if you have a small box with other heat producing devices, additional space and/or cooling may be needed.

A smaller PU resistor will be cheaper and use less space, but may not provide a solid, consistent output. Make sense??? Please 'Recommend Contributor' By the way, what is the application for these PUs?

it measures the ionization of the air.

An SCR is a Silicon-Controlled-Rectifier. SCR's are used to turn on the AC supply voltage to a motor part-way into the AC cycle, thus allowing only part of the cycle through. Although the peak voltage reaching the motor may be just as high, the average or RMS value is less, since the voltage is not on as long. This type of control is called phase-angle control, as opposed to frequency control, which VFD's (variable frequency drives) do. Note the word 'rectifier' in the name. An SCR, just like any other diode or rectifier, only conducts in one direction, so for AC motor control, two SCR's must be used, one reversed from the other. One SCR fires during the positive half of the cycle, the other fires during the negative half of the cycle. Once the SCR is turned on, it latches, or stays on for the rest of the cycle. When the AC cycle half completes, and the voltage crosses zero, the SCR turns off. Thus the gate signal is usually a very short pulse, right at the moment the SCR needs to fire. Note that the SCR is not like a transistor. It cannot be turned part way on, it is either on or off. The latching action is also different. Transistors do not latch on by themselves. SCRs can also be used as an on-off controller. In this case, the SCR is either completely off (when the motor is to be stopped), or it is controlled on for the entire cycle (when the motor is to run). This type of control is used to replace the old mechanical relays or contactors. In fact, these controllers are called 'Solid State Relays'. Again, two SCR's are used. A similar device is called the Triac. It works basically the same as an SCR, except it conducts in both directions, so only one is needed instaead of two.

There were a number of electronic devices on the market that were used for detecting a service fault, most notably, a product called, "Cyclops". However, the advent of high-definition television and high-speed video recording has rendered such devices obsolete. These new technologies include "MacCam" (a video system) and "HawkEye" (a mathematically inferred system). At tournaments where courts are equipped with these technologies, players are allowed to call for a limited number of "instant replays" of "in" or "out" calls they deem questionnable. Refer to the Wikipedia links, below, for further information.

A electric Geyser has a Element screwed in the side of the inner water container,

with the heated side submerged in water, parallel to the element (sometimes center)

is a thermostat unit to control the temperature by switching the element off once the desired temperature has been reached. The element itself is made with nichrome wire,

which is a resistive wire, When a Electric current is passed through the nichrome wire

the resistance of the wire restricts the current causing a pressure of electrons and protons (as water builds pressure in a hose pipe when the end is restricted) and intern

creates heat as a byproduct.

It allows your vehicle to start on when it is in park or neutral.

Signaling system number 5 is a take-off on the Bell System R1 multi-frequency encoding scheme adopted as a standard by the CCITT (from the French "Comité Consultatif International Téléphonique et Télégraphique" which translates into the International Telegraph and Telephone Consulatative Committee). Here's the scoop. A group of unique tones is put together to develop a "code" for use over a phone line. The tones are used in pairs, and the frequencies of the tones are selected to minimize the probability of harmonics being "seen" by listening equipment and being confused as another tone. For CCITT5, there were six tones selected and they were used in (15) unique pairs to transmit the digits zero through nine and also some instructions as regards the number string or the connection to be made. Ever use a telephone touch tone keypad? And hear the tones when dialing? Then you're familiar with something like SS#5 already. The keypad is a dual tone multi-frequency (dtmf) device. On touch tone phones, the keypad is three characters wide (the 1, the 2 and the 3) and four characters high (the 1, the 4, the 7 and the *). Draw a line across through each of the rows the characters, and then one down through each column of characters. Each line is a unique tone, and there are seven of them in all. Each of the characters in a given row has a common tone, but each row has a different one. Each of the numbers in a given column has a common tone, but each column has a different one. Each number that is pressed causes a unique pair of tones to be sent down the line. These tones can be interpreted by switchgear and the number (or instruction character) recovered. (Note: there is another vertical column of characters that are not on the keypad. They are the letters A, B, C and D down the right side of the keypad. There is a unique tone for them, too, and that makes our "matrix" four by four for sixteen unique characters. That gives the switchgear some other options for instructions outside the ten characters zero through nine, and the familiar "*" and "#" at the bottom of the first and third columns, respectively.) The particulars are cited in the Wikipedia article on Signaling System Number 5, and a link is provided to that and the DTMF article (the phone touch pad) to make comparing notes easier. Between the two articles and this answer, it is hoped that understanding follows.

It depends on whether the transistor is in the active region or not. Usually, the transistor would be in the active region when we are asking this question. if we look at the data sheet for the popular 2N3905 transistor, available at http://www.fairchildsemi.com/ds/2N/2N3905.pdf,

we see that if V collector-emitter is 10 V, the collector current is 1 mA, and the small signal frequency is 1 kHz, the typical small signal signal input impedance (which is nearly the same as small signal base-emitter resistance) is about 5,000 ohms. Under the same conditions, the typical output admittance, (which is nearly the same as the small signal collector-emitter resistance) is about 30 microsiemens. Calculate 1/0.000030 to find that this is the same as about 33,000 ohms, so in this case the collector-emitter small signal resistance is greater than the base-emitter small signal resistance. You might be able to find an operating point where the reverse is true.
