what are advantages of thevenin theorm?

It's a useful tool in electrical network analysis.\n\nAnother one is Kirchoff's law.

I presume we are talking electronics here. Nano technology implies that circuits are of the order of nanometres(very very small). The problems with this is that as the tracks in an integrated circuit (IC) get closer together they interfer with each other through heat, magnetic field effect and electric field effects. The benefits are that because track lengths are small the wires between components do not have to be treated as transmission lines (complicated) at the very high frequencies we demand of modern electronics. \n\nIn sum it is more difficult but gives better results.

Easy!\nIf the input is the same(1.1kW) it depends on their performance.

A voltmeter and an ammeter will provide the input power. You will need some form of dynamometer to measure output power.\n\nOutput power divided by input power yields efficiency.

Advantage: Can be mounted to the desk or monitor in the form of a Boom or Gooseneck. Microphones that utilize the bias power from the sound card do not need an external or battery power supply which is an advantage if you are trying to use one with an older model laptop.\nDisadvantage: Is typically a condenser microphone requiring an external DC power source. The sound quality is lower

If you place the batteries in series, you get more voltage (the sum of the individual battery voltages), but the current capacity remains the same.  If you place them in parallel, you likewise increase the current capacity, but the voltage stays the same.

Transmission of AC current is more efficient because it is easier to change to voltage. When delivering power over long distances the voltage is stepped way up (like 115,000 volts) because the current will be lower (for a given power draw). Lower current means less loss.

Using 3 phase current, it is possible to get 3 times the energy down the same wire - so it is much more efficient.  Each phase is 120 degrees out from the others, so the signal looks kind of like braided hair, when one phase is at the peak, the other two are crossing at 70%, one going up the other going down.  Once we get the energy to where we want to use it, then we can tap off the different phases for single phase use. \n\nI forget about the delta and wye stuff, it's been a while. \n\nCheers!

In order to use the generator more effectively a phase is spli into three namely R,Y,B. each 120 phase shift from other.\nThe power generated is transmitted by 3phase-3 wire system considering economy.\nIn distribution side there are low consumers for whom Single phase power feeding is inhalf. For them a seperate cnductor called neutral is provided ad a return path.\nNeutral also helps to balance the load during unbalaced loading/fault.\nNeutral is a point that is taken from the meeting point of three phases and is usually grounded to ensure balanced loading.\n\nIn dc +ve side is something where excess protonsr present and flow towards otherside and -ve side contains full of electrons which flow towards +ve side.\n\nu can visit www.play-hookey.com

Large Capacitor banks is one way.\n\nRegenerative Drives which take lost energy and feed it back in to the power grid has become much more popular based on the embeded logic controllers.\n\nInduction machines are terrible regarding power factor. Todays electronics has greatly improved the power factor loss.

Advantages - fast creation, easily modified and saves money\n\nDisadvantages - data can be lost or corrupted, needs backing up all the time.
