How much does it cost to fix an lcd screen in regular phones?
Depending on the phone it could easily be more than the cost to replace the whole phone.
When is sportfisher ultra450z fishing reel manufactured?
The Sportfisher Ultra450Z fishing reel is manufactured in various production runs, but specific details about its manufacturing dates can vary. Typically, these reels are available in the market depending on the brand's release schedule. For the most accurate information on manufacturing dates, it is best to consult the manufacturer's website or contact their customer service directly.
Your heating element is going out and that is why the fuse blew as well. You will need to have the heating element replaced in order for the dryer to work like it did when you bought it.
What is the application of ic 4001 quad 2 input nor gate?
Its a very versatile chip. It can be used in many places where logic control is required. As there are four identical NOR gates in one package, the inputs and outputs can be configured to make up quite complicated logic gates.
Being a NOR gate, the the output will be at supply level, until one or both of the inputs are taken high. At which point the output will go low.
The uses are many and varied. The 4000 series of chip are CMOS, so they can work at voltages between 5 and 12volts at low current.

A communication device is a peripheral used for communication between the computers and other devices. Modem is a popular communication device which is normally used for Internet communication. Infrared, Bluetooth and LAN card are the examples of communication devices.
A protective relay is a complex electromechanical apparatus, often with more than one coil, designed to calculate operating conditions on an electrical circuit and trip circuit breakers when a fault was found. Unlike switching type relays with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays had well-established, selectable, time/current (or other operating parameter) curves. Such relays were very elaborate, using arrays of induction disks, shaded-pole magnets, operating and restraint coils, solenoid-type operators, telephone-relay style contacts, and phase-shifting networks to allow the relay to respond to such conditions as over-current, over-voltage, reverse power flow, over- and under- frequency, and even distance relays that would trip for faults up to a certain distance away from a substation but not beyond that point. An important transmission line or generator unit would have had cubicles dedicated to protection, with a score of individual electromechanical devices. The various protective functions available on a given relay are denoted by standard ANSI Device Numbers. For example, a relay including function 51 would be a timed overcurrent protective relay. These protective relays provide various types of electrical protection by detecting abnormal conditions and isolating them from the rest of the electrical system by circuit breaker operation. Such relays may be located at the service entrance or at major load centers. http://en.wikipedia.org/wiki/Relay
Electromagnetic waves are transverse (unpolarized or polarized) or circularly polarized waves that have some electrical properties and some magnetic properties.
An electromagnetic wave consists of changing electric and magnetic fields. The repeated cyclic transfer of energy from the electric field (weakening it) to the magnetic field (strengthening it) until the electric field is gone, then from the magnetic field (weakening it) to the electric field (strengthening it) until the magnetic field is gone every cycle is the process by which electromagnetic waves propagate without requiring a medium (and is described in Maxwell's Equations).
Some are 24,36,and 48.Just keep adding it up by 12.
12, 24, 36, 48, 60, 72 and so on.
- 12 x 1 = 12
- 12 x 2 = 24
- 12 x 3 = 36
- 12 x 4 = 48
- 12 x 5 = 60
- 12 x 6 = 72
- 12 x 7 = 84
- 12 x 8 = 96
- 12 x 9 = 108
- 12 x 10 = 120
- 12 x 11 = 132
- 12 x 12 = 144
Multiples of 12 are any number that 12 can go in to. The first few multiples of 12 would be: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144

What kinds of problems do computers cause?
There are a number of problems computers can cause. Here are some of the areas of problems.
1. Health problems - If you're body is not well-supported while you use the computer, you could face problems with your wrists, back, shoulders, neck, etc. Eyestrain is a common computer problem too. If you have epilepsy, certain sounds and flashing images could possibly trigger a seizure.
2. Waste and environmental problems - Eventually, you will likely discard an old computer. It could go to a landfill and take up space if you don't recycle it. It takes petroleum products to make plastic, and quite a bit of plastic is used in computers. So if a petroleum tanker turns over and dumps its cargo in the ocean, that could harm wildlife and fish.
3. Mistakes, errors, and dangerous glitches - When the Pentium processors first came out, they had a problem with their floating point package, where certain mathematical computations resulted in grossly erroneous results. That could cause problems if you were trying to compute certain business or scientific things. However, there were workarounds to the problem, and that is not the most serious type of problem of this type.
Years ago, there were computers to give therapeutic doses of radiation to cancer patients. However, some patients were getting "cooked" by the radiation or facing lifelong problems after treatment. There were several reasons for this, and a number of safeguards and protections that were missed. The routines to take the input from the technician did not trap invalid responses. Some operators entered the wrong thing and then used the wrong key sequence to correct their error. However, they only blanked out what they typed, not really deleted it, and the computer took that as something other than the 2 valid choices given. The code of the program also contained "race conditions," meaning that there is a possibility that the data needed for a computation sometimes doesn't get where it needs to be in time. Then on the radiation and mechanical end of things, there were missing safeguards. It should have been impossible for both the high dose "antenna" and the low dose "antenna" to both be in operation at the same time -- but sometimes that happened, giving much more radiation than the intended high dose. There should have been interlock switches, physical barriers, or other protections in place.
Traffic lights are often controlled by computers. Imagine if the signals were contradictory, such as green lights in all directions. That could cause serious wrecks for sure.
4. Laziness - While humans are to blame for this, computers do make it easier, where you forget how to do certain things without a computer. In a typical store, if the power goes out and they only have emergency lights, most cashiers won't be able to ring up transactions, even if store policy says they could do it by hand.
5. Preoccupation, personal injury and carelessness - From time to time, there are stories of people texting or using other technology and jumping in front of cars, running into trees, etc.
How do you know when your capacitor is charged and ready for hook up?
The capacitor charges up when you initially install it and apply 12 volts to the circuit. Its purpose is to smooth out power drops in the 12 volt supply line to the amp. For instance, when the bass hits the speakers, the amperage surge can exceed the amperage the line delivers for a split second, so the capacitor supplies amperage briefly to sustain the power.
Hooking up a small motorcycle battery close to the amp serves the same purpose but is possibly messier because of the potential to leak acid.
Sabre is the name of the company that makes Sabre televisions. The company makes these televisions exclusively for the military.
State why it is important to do a PAT test?
PAT Testers Answer:
To answer the question above:
The Electricity at Work Regulations 1989; regulation 4 (2) requires that: "As may be necessary to prevent danger, all systems shall be maintained so as to prevent, so far as is reasonably practical, such danger".
Regulation 4 (2) is concerned with the need for maintenance to be done in order to ensure safety of the system if danger would otherwise result. The quality and frequency of maintenance should be sufficient to prevent danger so far as is reasonably practicable. Records of maintenance, including test results, should be kept throughout the working life of the electrical equipment to enable:
a) The condition of the equipment to be monitored.
b) The effectiveness of the maintenance policies to be assessed, and
c) To demonstrate that an effective system is in place.
All of this can be found in the IEE Code of Practice 3rd edition page 1.
