The pointer on a galvenometer moves due to magnetic force between the current carrying coil in the pointer assembly and the permanent magnet surrounding that coil.

A generator produces alternating current.

terminate the RJ11 end and on the RJ45 end crimp the 4 wires in the 4 middle slots. run the wires straight through, no crossover

The resistance of pure metallic conductors increases with temperature, because the resistivity of these conductors increase with temperature.

A Black Max generator (a portable gas generator manufactured by Honda) can be found on, for example, Amazon or Sears. Even ebay sellers offer deals on such machines. It is likely that larger hardware stores in your area stock these machines as well.

the rewireable can be dissembled and has some sort of chucks to hold a new element

half center bridge voltage

The 'field'winding is in the rotor which rotates at the synchronous speed generating AC powerat the right frequency in the stator. That requires DC in the rotor. It is convenient because the DC is supplied to the rotor through slip rings, smooth polished rings which allow the carbon brushes to last a long time.

It is kind of transformers called center-tap transformer its main function is to transform primary voltage to 2 secondary voltages or vice versa. In your statement the transformer will convert the input voltage to 2 voltage each is 9v or the opposite it will convert the 2 input voltages with each 9v to a certain value depending on the turns ratio of the transformer.

The California bearing ratio (CBR) is a penetration test for evaluation of the mechanical strength of road subgrades and basecourses.

The study of "Effect of soaking period and surcharge load on resilient modulus and California bearing ratio of gypsiferous soils" revealed that the resilient modulus increased with surcharge load and a correlation to soaked CBR was developed. The correlation between the strength ratio CBRL/CBR45 and surcharge load is insensitive to soil type.

Surcharge is the volume of the test, like weights testing how a balance works.

Use the equation V = I * R

20 = I * 5000

I = 20 / 5000

I = 0.004 Amps

The answer to your question is 4 mA of current will flow through the resistor.

Electric light bulbs use electric current to heat a filament to high temperature which produces electromagnetic radiation which appears to us as as "heat" in the invisible part of the frequency spectrum and "light" in the visible part. The alternating current (AC) voltage waveform changes at a frequency of 50 or 60Hz (cycles per second of a sine wave) depending on which country you live in. The filament stays heated from cycle to cycle of the AC voltage waveform - the highs and lows of the AC waveform are so close that the filament does not have time to cool off much. It thus seems to emit light continuously for us and we don't notice any reduction in light. One reason contributing to this is the persistence in vision of the human eye - we see anything happening at frame rate of 20 or more per second as continuous. If it were at a slower frequency of AC we would notice the changes in light intensity which occur at the different levels of voltage in the ac waveform.

Fan regulators are similar to light dimmers. Their function is to control the speed of the fan. The regulator uses resistances for the speed of the fan. It acts as a divider and the speed changes based on the resistance.

A 555 time circuit is a circuit chip that can be used for a variety of applications. some include: clocks, time delays, countdown timers, and other time-circuits.

The low pressure steam from the last stage of the steam turbine is condensed so that it can be pumped back to the steam raising units at high pressure, as water. You can't compress steam as it would condense in the compressor. The only way to use steam as a gas in a gas turbine would be if it was supercritical, but this would mean operating at temperatures well above the limits for most engineering materials, and steam at these conditions would be very corrosive. This type of reactor cycle using a gas turbine has been considered using helium as the working fluid, and it may be built as the "pebble bed" reactor, or it may not.

I think you need to understand more of thermodynamics. Read the Wikipedia entry for the "Rankine Cycle", see link below

One description would be forward biased.

The rule of thumb is 1mm square=6Amp so 10mm square will,for safety reasons and for a copper conductor, carry 50Amps.

0 volts.

It depends on the surround material, temperature, type of cable, and what you mean by "maximum current rating". Typically a maximum load current rating will be specified, such as 15A; this means you can push 15A through that cable nonstop without damaging it (it won't overheat). You might have a short time rating as well, such as a 4 hour rating, where the cable can handle runing 22A for 4 hours if the surrounding temperature is kept to some value, though this may slightly degrade the insulation. There's also a fusing current rating for many cables. At this current, the cable will eventually melt (like a fuse).
