How do you charge a AAA battery?
If it's a regular Duracell or Energizer battery, it's not recommended you charge them. Having said that, you could try using a NiCad charger, but DO NOT leave it unattended. If the battery is getting hotter than warm, stop charging it.
Your best bet simply would be to buy rechargeable batteries and a charger. SUre, they cost more at first, but it's bice not having to throw batteries away.
Who invented electricity and why?
I believe Ben Franklin was the one who discovered electricity with the kite and the key..but I'm not sure why.
+++
No - he realised the nature of lightning, but in fact many 18-19C scientists investigated electricity.
A multimeter has many parts. Some of these include the display, the controls, the probes, and the power source. Multimeters can be analog or digital.
Is there a difference between a regular freezer and a deep freezer?
Deep freezer is just a term for a style of freezer, in that's it's generally dedcated as a freezer without a refrigerator section. It may also be called `deep' because the freezer box is usually deep so that it can hold quite a bit of product.
Most deep freezers tend to have the opening in the top and can be a few feet wide and
usually a bit longer, and around 2 1/2 to 3' deep. Of course, there's varoius makes and models from which to choose.
ZIF sockets refer to the term, `zero insertion force', which is to say that the part being placed in the socket will usually just `drop in' at which point, some type of clamping system is used to hold the part in place. This is especially beneficial to parts where the leads could easily be damaged or malformed.
the capacitor has 2 wires or poles, one is the ground or negative and the other one is the hot or positive... if it is for car audio amp the ground is connected to the chassis and the positive is connected to the battery and to the positive wire of the amp.
Why did they invente electric cars?
Electric cars are more efficient than gasoline cars. Plus, it's cheaper to generate electricity to charge a battery that will drive a car for 200 miles (typically about a dollar) than it is to buy gasoline to make a car go for about 200 miles (typically about 20 dollars). However, all the BS about eco-friendly is a bunch of hot air unless you're not getting your electricity from a coal fired or natural gas fired plant. You're just moving your emissions to another place on the planet, not eliminating them.
How do you wire a garage sub panel box from a 100 amp breaker in the house main panel?
you propaly can't sub panel from 100 amp panel. Just not enough amperage to be worth while. i had to up grade t a 200 amp main first and then I was able to take a 60 sub panel from that.
Will super8 movie film work on an 8mm projector?
super8 works on super8 and 8mm on 8mm projectors, some projectors do have a switch to go from one to another
Can depletion mosfet act as enhancement mosfet?
It depends.
A depletion MOSFET can be used as an ehancemnet MOSFET when it is operated as an analog amplifier. However, a depletion MOSFET can't replace an enhancement MOSFET when it is operated as a digital switch.
When a depletion MOSFET is used as a digital switch, since the junction between source terminal and substrate must be reverse biased, the voltage of the source terminal of an N typde transistor must be tied to Vdd, and it is completely opposite to an enhancement MOSFET.
When a depletion MOSFET is used as an analog amplifer, the source terminal and the substrate are both at the same potential, just like an enhancement MOSFET.
Will the Keurig K10 Mini Plus Brewer work with a 100 watt inverter?
Highly Unlikely. Personal brewers like Keurig machines typically use over 1000 watts of power at a time to rapidly heat water. However you can see what a device's power consumption (in Watts) is if you look at the device's information sticker. The sticker may state the device's power consumption in Watts directly, or it may state the Voltage and Amperage that the machine runs on. You can multiply the volt and amp ratings to find out many watts the device might use (1000mA = 1A).
VoIP stands for Voice over Internet Protocol. It is also referred to as IP telephone or Internet Calling. It is an alternative way of making phone calls that can be very cheap or completely free. The 'phone' part is not always present anymore, as you can communicate without a telephone set. VoIP has been named the most successful technology of the last decade. People prefer to use VoIP for Pakistan for their call centers in order to provide the best communication medium.
HDMI will give you the best connection. It's a digital connection and not subject to loss like an analog connection. Depending on the age of your equipment, you may not have hdmi. If not, use component (red, blue, and green for video alond with red + white for audio) connections.
You didn't say which model Yamaha you have but if it's a newer A/V receiver, you can use it as a switch. Connect all the components to it and then one output to the TV input (again hdmi is best). This will make it so when you turn the receiver to an input, the video will automatically go to the tv. For example, if you put the receiver on DVD, the DVD video show up on the tv. This does mean that you have to have the receiver on to watch tv. I have mine set with hdmi inputs going through the receiver and component input to the tv from the dvr box. That way, if I want to watch the news and forgo the surround sound, you can put the tv input to component and just watch it with the regular tv speakers. If you need hdmi cables, monoprice.com is a good place to look. I have bought many from them and they are very high quality for a low price (around $15 for a 6'. Good luck.
Why is the secondary of a transformer a short circuit?
If you are saying that the secondary (output) winding on a transformer seems to be a short circuit, it is very likely to be low resistance and may only be a few ohms if you measure the resistance with an ohmeter. The only way it would actually be a short circuit is if something has been inserted which has shorted the wires or it has overheated and burnt through. In which case there should be an acrid smell. Or if you can see the wires you would see they were burnt.
A short in the circuit it is powering could cause the transformer to overheat, burn out and short.
If a bar of copper is brought near a magnet the copper bar will be what?
If a bar of copper is brought near a magnet and rubbed it will get magnetized and would behave like magnet. But this would be temporary and this property would wear after some days.
Will your radio still receive TV signals after 0209?
I've read both yes & no... I believe that you won't be able to hear TV sound, unless its a digital receiver radio...
How do you derive Friis' Formula?
I believe it can be expressed in terms of noise temperature instead of noise ratio. The noise temperature is directly proportional to noise power and inverseley proportional to the product of the bandwidth in question and Boltzmann's constant (which is a different derivation altogether).
--
I made an alternative derivation to the 'classical' one using noise temperature, where I avoid to use the noise temperature concept and only use noise power and noise factor:
Take a system which consists of two sub-blocks with power gain G1 resp. G2 (in case of a voltage amplifier for example G will be the square of the voltage gain A). In addition to the power amplification, each block introduces its own noise PN1 resp. PN2, in each case referred to the input of the block.
To the input of the first block is assigned a signal with noise power PNi1. The noise power at the output of the first block is PNo1 and at the output of the second block PNo2.
We can calculate the noise power at the output of the first block as:
PNo1 = G1 (PNi1 + PN1)
(i.e. the block amplifies the input noise and adds some noise of its own)
Similarly for the second block:
PNo2 = G2 (PNo1 + PN2) = G2 G1 Pni1 + G1 G2 PN1 + G2 PN2
We can also consider the two blocks together as a 'black box' with power gain G1*G2. We can then calculate the output noise power as follows:
PNo2 = G1 G2 (PNi1 + PN12)
Where PN12 is the effective noise power (input-referred) added by this 'black box' consisting of the combination of the two blocks. Combining these 3 equations gives us immediately:
PN12 = PN1 + PN2/G1
This already shows clearly the principle of the Friis equation, namely that the noise of subsequent stages is reduced by the gain of the preceding stages.
Now we will express this formula in function of the noise factor F.
Noise factor F is defined as SNRi/SNRo = (PSi/PNi) / (PSo/PNo). This combined with the fact that the signal power PSo = G1 * PSi leads us to :
F = 1 + PN / PNi <==> PN = (F-1) PNi
This also clearly shows us that an ideal noiseless stage would have a noise factor F of 1 (this is of course not possible in reality, so F will always be greater than 1).
If we write this equation for the first block:
PN1 = (F1-1) PNi1
And for the second block keeping in mind that the noise factor F2 is defined for this second block as if we were applying the input noise directly to it:
PN2 = (F2-1) PNi1
And last we write the equation for the 'black box' combination of both blocks:
PN12 = (F12-1) PNi1
We now set this last equation equal to the previous equation we derived for PN12 and fill in the other two:
(F12-1) PNi1 = PN1 + PN2/G1
F12-1 = (F1-1) + (F2-1)/G1
F12 = F1 + (F2-1)/G1
That gives us the Friis equation for a cascade of two blocks. This can easily be iteratively expanded to any number of stages to give:
Ftotal = F1 + (F2-1)/G1 + (F3-1)/G1G2 + (F4-1)/G1G2G3 + ...

Why would the engine light stay on in a 2005 pantiac vibe?
Mine is on because the oxygen sensors are having an issue. Just took it in to be checked goes in next week to be fixed. Also received a recall couple of months ago I took it in for but I doun't remember what part was replaced.
How many outlets on 15 amp breaker?
As many as you want. It is the power consumed by the thing(s) plugged in that is of concern.
