What are the advantages disadvantages of analog to digital converter?
An advantage to switching to digital television is that it is a precise way to deliver television signals. A drawback is that everyone couldnâ??t upgrade and some people had to buy additional equipment to watch television.
What is Quasi Square wave or Modified Square wave Inverters?
Quasi Square Wave or Modified Square Wave actually mean the same thing. Modified square wave is the actual wave form. Quasi Square Wave is a marketing term used by many low cost inverter manufactures.
Inverters convert Direct Current DC to Alternating Current AC. Old obsolete inverter technology created square wave output. As stated by the name the wave form is square not sinus as required to have pure sine wave AC. Modified square wave has a step or dead space between the square waves. This reduces the distortion or harmonics that causes problems with electrical devices. Modified Square Wave inverters will work fine for pure resistive loads, like lamps or heaters. It will also work well with pure inductive loads, like universal motors in mixers and blenders. If these devices have electronic speed control this could be damaged. Devices that have transformers in their power supplies, Microwave Ovens, TVs, Computers etc. will run hotter and less efficient. These devices will not last as long as the would on pure sine wave inverters. For the money the modified square wave inverter will cost more in the long run by reduced efficiency and possible damage to appliances. I highly recommend that you use a pure wave inverter it will cost less by increased efficiency, problems and possible damage to your appliances.
How can you make a current smaller in a circuit?
Taking some bulbs out of the circuit!! (I think :P) Taking some bulbs out of the circuit!! (I think :P) Use Ohm's law I = E/R. Add some values and check it out.
You use the formula V = IR (where V and E are the same thing, voltage. I is the current. R is the resistance). If you add more resistance then your current will be lower. I would suggest looking at parallel and series resistance so that you can understand equivalent resistance.
To hear a radio 100 of miles away from the source when the frequency is 1000kc it would require antenna of tremendous size and bulk. So the idea is to transmit a very hi frequency and vary that frequency by 1000kc and then get rid of the carrier frequency and hear the modulation frequency only or 1000kc in this example.
DIGITAL refers to two 2 states a '0' and a '1' OR false or true also known as binary and machine language. Analog can have infinite states and magnitudes and polarity including phases relationship.
if it's volt per ohm a ma would be 0.000001 of volt per ma
that is incorrect .000001 is a micro-amp not ma. besides you need two units to solve it Basically it is a ratio 1:1:1 1Ohm 1Volta 1Ampere NAMED AFTER THE DISCOVERY GUYS
What kind of wave does a microphone make?
A microphone does not generate waves but Rather generates a stream of electrons. Waves needs a medium to propagate like air & water. A broadcasting station does send waves as electrons signals but the medium is not physical
There are several methods for generating FM signals but they all basically involve an oscillator with an electrically adjustable frequency. This type of oscillator uses an input voltage to affect the frequency of its output. For example, when the applied voltage increases, the oscillator output frequency increases and when the applied voltage decreases, the oscillator output frequency decreases as well. If no voltage is applied to the oscillator its output will be a signal at its centre frequency. The amount of frequency variations is deviated around the oscillators' centre frequency.
The electrical conductivity of metals which is expressed in ohm-1 m-1 is of the order of?
In the range of 1 x 10^7 1/ohm-m . That's one times ten to the seventh power.

A current of 200 micro A through a 6.8 k ohm resistor produces a voltage drop of?
1.36 volts Ohm's Law: Volts = Amps * Ohms
1/2 watt (In theory you could use a "0.27 Watt" resistor, however there would be no safety factory and there is no standard value resistor that size.)
What are Cellugraf Signals used for?
Cellugraf signals were used for identifying pages in a book. They were very popular prior to the 1960s and were essentially used in place of placing a paperclip on a page to mark it. In fact, I am looking for Some Graffco Cellugraft Signals for a project I am doing.
Can resistors function the same in AC circuits as in DC circuits?
Yes, they both can add a load to a circuit.
When use undervoltage release?
Under voltage protection (release?) is used in industry. If there was a power failure and a piece of equipment was running when the failure occurred for safety reasons the machinery should not start up on its own when the power returns back on. With under voltage protection the operator restarts the machinery after checking that there is no danger to anyone and the machine is clear to start. To obtain this safety feature an electrical contactor is used in conjunction with remote stop - start buttons located at the machine the operator is working.
Unintended high current closed connection between two points in a circuit?
A short, or short circuit.
What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
Working parts of electric iron?
There are three main working parts
Heating element, sole plate and pressure plate are the working parts in electric iron.
These three parts are same in even in automatic electric iron.
