What is RMS,Peak,Peak to peak,Freguency and Wave length?

The RMS velocity is exactly what is sounds like, it is the square root of the mean velocity of all the particles within a system. How one would determine the RMS depends very much on the system that one is dealing with.

Peak amplitude

In audio system measurements, telecommunications and other areas where the measurand is a signal that swings above and below a zero value but is not sinusoidal, peak amplitude is often used. This is the absolute value of the signal.

Peak-to-peak amplitude

Peak-to-peak amplitude is the measure of the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative). Peak-to-peak amplitudes can be measured by meters with appropriate circuitry, or by viewing the waveform on an oscilloscope. Peak-to-peak is a straightforward measurement to make on an oscilloscope, the peaks of the waveform being easily identified and measured against the graticule. It remains a common way of specifying amplitude but sometimes other measures of amplitude are more appropriate.

FREQUENCY is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. Loosely speaking, 1 year is the period of the Earth's orbit around the Sun, and the Earth's rotation on its axis has a frequency of 1 rotation per day.

In physics, the WAVE LENGTH of a sinusoidal wave is the spatial period of the wave – the distance over which the wave's shape repeats. It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns.

AC sine wave

In alternating current (AC, also ac) the movement (or flow) of electric charge periodically reverses direction. In direct current (DC), the movement (or flow) of electric charge is only in one direction.

Used generically, AC refers to the form in which electricity is delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave, however in certain applications, different waveforms are used, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. In these applications, an important goal is often the recovery of information encoded (or modulated) onto the AC signal.

FLUX LINES

flux

Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field . Flux is depicted as "lines" in a plane that contains or intersects electric charge poles or magnetic poles.

*flux lines moves north to south.
*they never intersect each other.
*they can`t be broken.
*they always try and shorten.

HOW TO SOLVE RESISTER NETWORK

# Thevenin's Theorem is a way to reduce a network to an equivalent circuit composed of a single voltage source, series resistance, and series load.
# Steps to follow for Thevenin's Theorem:
# (1) Find the Thevenin source voltage by removing the load resistor from the original circuit and calculating voltage across the open connection points where the load resistor used to be.
# (2) Find the Thevenin resistance by removing all power sources in the original circuit (voltage sources shorted and current sources open) and calculating total resistance between the open connection points.
# (3) Draw the Thevenin equivalent circuit, with the Thevenin voltage source in series with the Thevenin resistance. The load resistor re-attaches between the two open points of the equivalent circuit.
# (4) Analyze voltage and current for the load resistor following the rules for series circuits.

Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur very frequently. Components connected in series are connected along a single path, so the same current flows through all of the components.Components connected in parallel are connected so the same voltage is applied to each component.
A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit.
In a series circuit , the current through each of the components is the same, and the voltage across the components is the sum of the voltages across each component.In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.

This our Learning Styles group asignment we did earlier in the year before easter break. Me,michael,david and vinoth was in our group.Michael writen about the the facters that efect our learning,me written about what are 3 learning styles,david did the summery and vinoth did all the computer work and designs.We managed get a passed mark in this asignment....

Veroboard layout

The resistor color code is a long standing standard in both the electronics and electrical industries, indicating the value of resistance of a resistor. Resistance is measured in ohms and there is a foundation for it called Ohm's Law. Each color band represents a number and the order of the color band will represent a number value. The first 2 color bands indicate a number. The 3rd color band indicates the multiplier or in other words the number of zeros. The fourth band indicates the tolerance of the resistor +/- 20%, 10% or 5%. In most cases, there are 4 color bands. However, certain precision resistors have 5 bands or have the values written on them, refining the tolerance value even more. There is no standard (TANS) however, for the 5th band. From one manufacturing company to another, the 5th band may indicate 2%, 1%, 1/2% or even closer, according to their own standards. Color bands are usually found on resistors that have a wattage value of 1/8 to 2 watts; though it is rare, there are some 5 watt resistors that are banded. There are also some capacitors that are color coded.

Conclusion

My hypothesis was correct. The nichrome wire has a higher resistance than the copper wire and the longer the wire, the higher the resistance.

Ohm's law states that the current flowing through the circuit is directly proportional to the voltage applied. (If you double one, you double the other.)

I worked out the resistance of the wires by using the formula:
V/I = R or v = I x R

computer ergonomics

Ergonomics is the science of designing the job, equipment, and workplace to fit the worker. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability.[1]

previous week on Thursday march 25th we learned how to make electricity from lot of different sources.we also did a internet research assignment about Germany's EMF sources......

we learned few things last week specialy abt vectors....

previes week we learned some usefull stuff in computing,handskills,soldering and electric theory classes.....

jana report

The week gone we started our first computing class with Mr Phil Plunget..We learned to login to unitec computing system and learned about black board its really help full for all the students and also we greated new Gmail account.In the afternoon we had PDV class also with mr Phil..2nd day we had Electric theory and drawing..Wednesday we started soldering with mr Sunil we did some cool stuff in there. In the afternoon we had PDV class..Last day morning class started with electric theory and finished with hand skills in the afternoon with other Mr Phil we learned some Drilling drawing on the metals kind of useful stuff there.

hi my name is jana. im doing electrical course in unitec this year..i want to be a electrician in the future.
