Have you ever had a soldering iron roll off the table and land on your wrist, burning a hole that took over a month to heal? I did in 5th grade while building one of the Radio Shack electronics kits I had received for Christmas!

Learning from that I made my own soldering stand from a small metal can and poured over a half inch of lead into the bottom from my lead soldier casting set to make sure that the weight of the soldering iron could not tilt the soldering stand!!! I was never going to run the risk of a soldering iron getting away from me again!!!!!

PICs are microcontrollers made by Microchip, Inc. PIC microcontrollers are used mostly in embedded control applications. Microchip offers hundreds of different PIC devices from tiny 6 pin packages up to 121 pin devices. The PIC line is offered in several families, based on an 8 -bit, 16-bit, or 32-bit core processor with various sets of peripheral and interface hardware on the chip. Each PIC has a processor, program memory, data memory, on board clock circuitry, timers and inputs and outputs.

Depending on the device chosen, the memory, operating speed and I/O capacity will vary. Additional functions may include A-D converters, serial ports, USB ports, external memory access, pulse width modulation, Ethernet ports, comparators, voltage references and more.

Because of the small instruction set and free assembler, PIC programmers often use assembly language to write programming. Although some higher-level language tools are available, languages like C are difficult to implement on some PIC devices because of hardware limitations, like a small fixed stack memory.

A vast amount of application and technical data is offered by Microchip. See the website at the link below.

This is essentially a thermocouple, which is a junction between two different metals. These are used to measure temperature in some piece of equipment where you can't introduce a thermometer, and can provide a remote indication of temperature. If a large number of thermocouples are assembled you can get enough current to operate small devices, this assembly is called a thermopile.

Its not recommended. A four ohm speaker cabinet can be changed into an eight ohm speaker cabinet, if you have enough speakers in the cabinet in parallel that can be rewired in series. Unless you have a high end cabinet, the likelihood of this is small.Two four ohm cabinets, however, in series will be eight ohms. Keep in mind, however, that doubling the resistance will halve the current, which will quarter the power. Also, changing the impedance of a speaker system will change the frequency response, because often the filters are tuned with resistors.

This is an electronic device which converts electrical signal into a digital signal.

1080p and 1080i both refer to the format of a video signal. Any HD television will receive the signal and display it. If the television reports the signal standard being received, it will let you know what the signal is. Therefore, the television cannot be changed from one standard to another as it simply handles the incoming signal.

Currently, broadcast HD signals are almost exclusively 1080i with a few formatted as 720p. Both are considered full HD even though the resolutions are different. 1080p is found on some local sources such as games consoles and Bluray players but has not yet made it to mainstream broadcast services.

infinity- so that all the voltage is measured across the component instead of losing some in voltometer circuitry

There's not much good things about a series circuit, but here's one that i know about. A series circuit has more than one power source or output device. It uses a single path to connect all the devices. An advantage of a series circuit is that you can add more power devices, such as more batteries, and increase the force of the output. This will give you more power.

P.S. If you wanna see a bad thing about a circuit, then just type, What is a bad thing about a series circuit? in that box thingy.

Wind turbines do not save any money. As of today, the overall cost of a kiliowatt of wind power is still higher than most other forms of energy. What wind is trying to save is the amount of fossil fuels we are using. Payback on wind is still not a feasible concept, although the numbers are getting better.

-> frequency shift keying promotes long distance communication.

->it has high security.

->low noise

->efficiency is high.

->decoding of signal is easy.

You get a properly sized low value resistance of high accuracy like 1% known resistance say 1 ohm.

Then you place the wire that you want to measure in series with the resistor and place the voltmeter across the resistor.

So if you have a 1 ohm resistor and the meter is reading 1 volt then you have 1 amp flowing in there.

you need to unhook the negative battery cable and set your mutimeter to amps and connect it between the negetive cable and the battery and that will tell you what kind of draw you have just make sure that your multi meter is set up right

You can't measure the current drawn by a car. The current is WAY to high for most meters. Most meters will only measure up to 10Amps. The first guy has the best idea. Get a 1ohm resistor and measure the voltage across it. The voltage measured divided by the resistor value equals the current consumption.

If you have to use a voltmeter the first answer is right just make sure its a 5 or 10 watt resistor at least and don't turn the key definitely.Just measure for current being taken that shouldn't be.

And yes you can use an ammeter to measure the current make sure its on the correct range (1 amp or 10 amp is better) and don't turn the key just check for current being drawn other than the starter and relay.If you turn the key big trouble lol.Probably burn out the meter burn yourself if using a resistor or just not good :) And don't wory about a 1% resistor 5% or 10 % is fine to just get a good idea of the amount of current.

Transformers require changing magnetic flux to operate. DC current provides a steady current, with no changes in magnetic flux that can be picked up by the output coil.

Alternating current has continuously changing direction which produces continuous changes in the magnetic flux. This induces changing voltage in the output coil. This is (or was) the huge advantage of AC power systems worldwide: The voltage could be easily changed from high voltage for generation and transmission into low voltage at the consumer. DC generators had to run at the voltage required by the consumer and powerlines could not be higher voltage / lower current than the consumer.

Today, switching systems easily convert DC to other DC voltages, DC to AC, etc. This is done in most computers, telephones, stereos, etc. It can even be done on a grand scale, allowing use of high voltage DC power lines in selected places.

Because resistor is not required to operating voltage.naturally resistive material like carbon is restrict of voltages.Active components means its requiered to operating voltage or Vcc or Vdd example transistor and fet etc..

A2

Passive components need no external control inputs. They have a natural effect on a voltage applied to them.

A3

Resistor are called passive component because their resistance value does not change even when the level of applied voltage or current to it is changed.also resistance value remains same when the applied voltage ac or dc.

short or short circuit

A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.

A synchronous counter is not

referred to as a ripple counter. They are two different things. The ripple counter uses the output of each stage to trigger the input of the next stage, resulting in propagation delay between stages. The synchronous counter, on the other hand clocks all stages on the same clock edge, making them all change at relatively the same time.

In the manufacture of PVC cellular plastic, a liquid plastic mixture is admixed with fibres in an amount of at most 0.050 percent by weight fibres, preferably carbon fibres having a length of about 1 cm, which fibres are distributed in the expanded cellular plastic isotropically with respect to both position and alignment. The cellular plastic is effective to dampen electromagnetic radiation within the radar range to at least 1-3 dB per cm.

I suggest your local electronics parts jobber, or one of the mail order or internet electronics parts stores (e.g. Mouser, DigiKey, Jameco Electronics).

In what sense.

at higher values of temperature the intrinsic carrier concentration become comparable to or greater than doping concentration in extrinsic semiconductors. thus majority and minority carrier concentration increases with increase in temperature and it behaves like intrinsic semiconductor.

· It is not recommended for use above 70° Celsius although it can be taken to 80° for short periods. · Sensitive to UV and oxidative degradation. · Limited thermal capability. · Thermal decomposition evolves HCI. · Higher density than many plastics.

If the switch is open, current does not flow.
