An autotransformer is no different than a regular transformer. It has "effectively" two windings, a primary and a secondary. Its just that one end of the primary is connected to one end of the secondary. It can also be said that it has only one winding, and that there is a tap someplace in that winding, but the end result is the same. Depending on how it is connected, it can step up or step down the voltage. Some autotransformers have multiple taps. Some, called variacs, have a sliding contact that allows relatively fine control of the output. The up side of an autotransformer is that it can be easier to build. The downside is that it does not provide electrical isolation between primary and secondary, nor can it filter harmonics as well as a dual winding transformer.

The fundamental difference between a potentiometer (pot) and a rheostat is that the former is a three terminal device, while the latter is a two terminal one. Let's look at both. When we consider either device, we are looking at a resistive element with a "wiper" or "adjustable contact" to which we can attach a wire. The only difference between the two devices is that the resistive element can have an electrical contact (terminal) at both ends or at just one end. The pot has terminals at each end of the resistive element, and the rheostat has a terminal at only one end. Lastly, a pot can be used in place of a rheostat, but not the other way around.

In DC inductor is short circuited .

AC. is alternating current and Dc is direct current. alternating equivalant to pulsating electricity while direct is a constant draw with little fluxuation.

2. Half wave and full wave

60898 is an IEC standard; there are two parts. 1 is for AC, 2 is for DC.

IEC 60898-1 "applies to a.c. air-break circuit-breakers for operation at 50 Hz or 60 Hz, having a rated voltage not exceeding 440 V (between phases), a rated current not exceeding 125 A and a rated short-circuit capacity not exceeding 25000 A."

IEC 60898-2 "gives additional requirements for single- and two-pole circuit-breakers suitable for operation with direct current, having a rated d.c. voltage not exceeding 220 V for single-pole and 440 V for two-pole circuit-breakers, a rated current not exceeding 125 A and a rated d.c. short-circuit capacity not exceeding 10000 A. This Part 2 is to be used in conjunction with IEC 60898-1." (quotes taken from IEC abstracts)

I think the cause of ripple voltage would be from a bad ground or capacitve voltage.

A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.

very high value

In the US, I've always heard it "AM-peer" (1st syllable like "I am" and 2nd like "pier"). It's actually the name of a French scientist, so I'm sure it's been Americanized.

The plural would then be "AM-peerz".

The transition time in digital electronics is in the order of nano seconds.

Most new automobiles today use a single 12 VDC electrical system with the negative terminal of the battery grounded to the frame of the auto.

By using Ohm's law, you are able to find the resistance of a circuit, knowing only the voltage and the current in the circuit.

In any equation, if all the variables (parameters) are known except one, that unknown can be found. For example, using Ohm's law, if current (I) and voltage (E) are known, resistance (R) the only parameter not known, can be determined:

Basic formula:

Remove the divisor by multiplying both sides by R:

Result of step 2: R x I = E

To get R alone (on one side of the equation) divide both sides by I:

The basic formula, transposed for R, is:

Mathematics is the language of engineering (as well as science).

The induced current is proportional to applied voltage. i is proportional to v

Or you might say, "A current source drives a fixed current through a circuit. Then the voltage developed is proportional to i" . Both forms are equally correct. Voltage sources are more common than current sources so the first form is more common.

Diodes normally drop between 0.2 and 3.5 volts in the forward bias direction, depending on type, and forward current. The word "ouccuer" is not understood". Please restate the question.

Full load current can be calculated by the formula given below: P=SQUARE ROOT OF 3*V*I*POWER FACTOR P=1.732*V*I*PF suppose 3 kw motor three phase voltage assuming .85 power factor and 415 volt full load current will be 3*1000=1.732*415*I*.85 I=4.9 ampere(full load ampere)

A radar gun or speed gun is a device used to measure the speed of different objects. It might by a traffic officer to clock a vehicle's speed. Or perhaps a TV network is using it to clock a baseball pitcher's fast ball. The applications vary, but the unit works by applying the Doppler effect to discover how fast something is going. Basically, the unit sends out a signal and looks at the return signal. It compares the frequency of the returned signal to the transmitted one, and the difference can be "converted" into a speed.

The electric field is stronger near the electron and becomes weaker as the distance from the electron increases.

The question needs some clarification / elaboration. The actual power in a resistor depends on how much electric current passes through it. There are plenty of topical (electronics type) web pages that provide a detailed technical explanation. Try Wikipedia. Or browse the technical section of your local library. A more useful question might be - "What value of resistor power rating should I select for a particular application?". So a secondary question would then be - "What is the application?".

i think the libraries of the multysim is only read

that's my previous though

but now i get libraries of multisim 11

so

hope that work :)

No.

At 110 volts it is 0.8 amps. At 220 it is 0.4 amps. I=E/R. I=amps.E=volts R=resistance.

In compressive load cell weight is applied on load cell and it gets compressed. Due to this compression we can measure the applied load. You can check out at http://www.adiartech.com/compression90210.html

and in tension load cell see this link that i came across
