In power supplies both coils and capacitors are used to smooth the pulsing DC output.

settlers in america often faced challenges while building new communities. In the 1760s, new orleans was the capital of spanish colony of louisiana. sailors from the philippines served on spanish trading ships going between manila, the capital of the philippines, and acapulco, mexico.

Thyristors are preferred in applications that require the characteristics on a thyristor. Thyristors are quite different to transistors, when they turn on, they stay turned on untill the power source is removed. Transistors conduct as controlled by the emitter current.

No-one 'discovered' the volt. The volt was named in honour of an Italian physicist, long after his death.

It all depends on the load. The formula for calculating amps, volts or ohms (resistance of load) is E=IR, where E is the voltage, I is the current and R is the load or circuit resistance. So, if you know the resistance in ohms and the current in amps, you multiply them together to get the voltage of the circuit. Again, it depends on the load, so a 12 volt car battery can deliver 1.5 amps if the load is 8 ohms whereas a 120 volt circuit will deliver 1.5 amps if the load is 80 ohms. This is all simplified and is based on a resistive load. If the load is capacitive or inductive, then phase angles come into play and the math is more complicated using imaginary numbers and J-operators.

Graphite is a non metal conductor.

In general, a valve (as in thermionic), a tap or gate valve (as for water).

Or perhaps just a constriction.

Resistance in an electrical circuit.

A shaped nozzle is important for some purposes such as a garden hose, or as in sand blasting process.

it is one of method to turn off scr. resonating LC component is used to turn off scr

First of all that's an incomplete question, in fact it could hardly even be called a question. Nevertheless I will attempt to answer what I think the question might be.

A Frequency to Voltage converter simply converts a frequency to a voltage as the name would imply. The voltage output will vary linearly with the frequency input (assuming it was designed properly). They can be useful in devices such as tachometers or speedometers.

Here's one example of a such an IC:

In physics, an alpha emitter is a radioactive substance which decays by emitting alpha particles.

Simply Stated: As electrons move across a wire, they constantly collide with atoms making up a wire. These collisions impede the flow of electrons and are what cause the wire to have resistance. Thus, if the diameter of the wire were larger, it would only make sense that the electrons don't collide as much, therefore creating less resistance due to a larger wire. This is all in accordance to Ohm's law. The resistance is the ratio of the voltage difference across an object to the current that passes through the object due to the existence of the voltage difference. If the object is made of a material that obeys Ohm's Law, then this ratio is constant no matter what the voltage difference is.

Consider a copper wire that passes some amount of current, say 1 A, when a voltage difference of 1 V is applied between the ends of the wire. Now consider an identical but separate wire connected across that same 1V potential difference. You would expect that it would also conduct 1 A.

Now think of joining those two wires together side by side into one, thicker wire. It is reasonable to expect that this wire should carry 2 A of current if the potential difference across the wires is still 1 V. Thus, the new, thicker wire will have a reduced resistance of 1/2 Ohm compared to the original wire with its resistance of 1 Ohm.

Basically, a thicker wire creates additional paths for current to flow through the wire.

They are sandals that have a piece of plastic or cloth that goes between your toes. They are also called, though not by me, foot thongs, for that very same in between the toes thing.

In New Zealand they are called Jandals ( short for Japanese sandals).

The resistance of a forward biased pn junction is zero.

To convert Direct Current (DC) to Alternating Current (AC) requires that you create a oscillator circuit (60 cycles if you're making 60 Cycles AC). This would require somewhat sophisticated oscillator circuit using power output SCR's or transistors to cause the DC source to switch on and off. Often this is done a 12 VDC and then the resulting 12 VAC waveform is input into a step-up transformer and creates 110 VAC.

Variations to this design occur depending on the base input and output voltages, and what output waveform you need (Sinewave is most common). To create a sinewave requires wave shaping filters and additional design considerations.

DC to DC step-up converts work on the same principles with the only difference (from above) being that the higher output AC voltage then gets rectified back to DC.

Series DC motor develops a very large amount of turning force called torque from standstill and can be operated by using either an AC or DC power source.

Almost 17% of Americans own a GPS device, whether in their car or on their phone or other wise. An approximate number would be around 3,065,849 people, and the number continues to climb. (Maty 2013)

They will both last for the same amount of time, assuming that the voltage across the individual bulbs is the same in each case. In both situations all of the battery's power Is being used, but In parallel, you can separately control the Individual loads that you put on the circuit with switches.

There are more than one type of loud speaker but the most common is a coil of wire suspended in a magnetic field. When alternating currents are passed through the wire, resulting vibrating magnetic fields push and pull against the permanent magnet. The coil is connected to a surface, usually conical, which moves back and forth because of this pushing and pulling causing sympathetic sound vibrations in the air adjacent to this surface which then move away as sound waves.

Use the formula P = I2R (I = current; R = resistance).
