Does decreasing the Ohms on a subwoofer add to the RMS?
No. Reducing the resistance of a sub woofer effectively means that more power is available from the amp. It does not improve power handling of the sub itself. In order to improve power handling of a sub, you need to improve its ability to manage heat.
In the audio industry, companies generally improve heat management by giving their subs large diameter voice coils and more massive magnets. The large voice coil provides more surface area from which to radiate excess heat. The more massive magnets provide both greater magnetic field strength and more mass with which to absorb the heat from the voice coil.
Mr. Van said: The impedance of the speakers must match the output impedance of the amplifier or there will be wasted power loss, usually converted to heat. This heat sometimes damages the output transistors or integrated circuits in the amplifier, or the speaker, or both. Some amplifiers have protection circuits that may prevent this by blowing a fuse, tripping a breaker , or just reducing the output power.

How might you apply each of the four steps in the system of textbook reading, located in the A Plan for Active Reading section of Ch. 7, to reading text on your computer? The four strategies for Active reading are previewing, marking, reading with concentration and reviewing. Applying these techniques to reading text on a computer screen is simple in some aspects and different in another. College students will have to adjust a few active reading steps so they apply to computer reading. Previewing is looking over a chapter for the introduction, summary, heading, sub-heading, and connecting it to the knowledge the students already knows. Reading the assignment online or in a book is similar for most college students concerning previewing. Here are several techniques in previewing that serve useful in computer reading, mapping, outlining, and listing. ]
What waveform is best and why?
different waveforms are used for different purposes i.e a sinewave can be used to test the frequency response of an audio amplifier or act as a 'trace' signal to find a fault in an audio amplifier. Square waves can be used in digital circuits as a pulse or as a binary code.
What is the conversion of amp to mA?
amp = ampere
mA = milliampere (or "milliamp" for short)
1000 mA = 1 A = 1 amp

Without hysteresis, computers would have no memory (either short term or long term), and even if I were fast enough to type this message completely before my computer forgot about it, there would be no way for you to read it without a storage disk, which basically works of some sort of hysteresis (most probably ferromagnetic)
hysteresis is "a dependence on the past": it's memory.
What is the dis advantages of calomel electrode?
It cannot be used above 50 degree because the Hg2Cl2 breaks down,yielding an
unstable readings.
Mercurous chloride used in calomel electrode is a toxic substance
The dials usually measure the Kilo Watts you have used in 1000's 100's 10,s etc. Each dial should say what they are measuring but they go up in numeric order.
The cost is not so easy to work out as most electricity companies charge more for the first few hundred KW you use, to cover their business costs, then the price per unit (per kilowatt hour) will drop for the rest of the billing period.
The best way to estimate this is to see how many KWh you used on your last bill and the total cost including taxes etc then you can work out your average cost per KWh (a 1 KW heater on for 1 hour is a KWh).
It is only a guide because if you use more or less power then the unit cost will change, electricity companies are also changing their prices very often to make your calculations redundant and difficult.
Have you thought of a smart meter?
Are red laser beam harmful to child?
Class I lasers are not harmful to the eye. Class II lasers are only harmful if the blink reflex is defeated. It doesn't make any difference what the visible color is. UV lasers can be dangerous at very low power output.
If your kid chases the light and runs into walls or falls off of long drops, you should avoid that.
Is wire a component in an elictical circut?
You probably mean "electrical".
Wires are not usually thought of as components, since wires just connect between components.
If you look at a circuit diagram, the wires are usually just simple lines, showing that they are only there to convey current/voltage between the more complex components.
Wiring can affect how a circuit works, but this is not a desirable thing. Designers will usually select wiring that has the *least possible* effect on the circuit.
How can ICT affect your life in a positive way?
You can social network with your friends when you haven't seen them for a long time, or you can learn educational stuff from the internet or computer educational games. There are way more reasons. Basically everything you can think of that you learn in school!
How much money is the Leica V-LUX 40?
The Leica V-Lux 40 compact digital camera typically has a street price of $700-$900 (as of 2012).
How much time does the average person spend using on electronics?
normaly pepole use it almost 2h. for me, its 5 to 10h =)
Why are clampers known as DC restorers?
A clamping circuit will bind the upper or lower extreme of a waveform to a fixed DC voltage level. These circuits are also known as DC restorers.
How do you adjust the sensitivity of a photoresistor?
You probably can't.
The sensitivity will be a result of the manufacturing process. It may vary from one photoresistor to another, even of the same type, and it is probably temperature-dependent.
But in terms of adjusting the actual sensitivity to some exact value.
No.
How do you go pot farming in rotmg?
Kill gods, grind dungeons, have alt account for holding pots (or just drink the pots)
What does the third and of a resistor mean?
That depends on the resistor, the resistors that are color coded come with either 4, 5 or 6 bands.
On resistors with 4 bands, the 3'rd band is the multiplier.
F.ex if we have a Resistor colored brown:red:orange it would mean 1 : 2 : 3 which translates to (10+2)*10^3, or 12*1000 = 12k Ohm
On resistors with 5 or 6 bands, the 3'rd band is just another digit
For examle a 5-band resistor starting with brown|red|orange|yellow would mean
1 | 2 | 3 | 4 which translates to (100+20+3) * 10^4 or 123*10000 = 1,23M Ohm
