What are the uses of transformer?

1.) It can rise down the level of level of Voltage in an AC Circuit.

2.) It can build or decline the estimation of capacitor, an inductor in an AC circuit.

3.) It can accordingly go about as an impedance exchanging gadget.

4.) It can be utilized to keep DC from going from one circuit to the next.

5.) It can seclude two circuits electrically.

Is there any way to detect an electronic bugging device?

Sometimes. When we "sweep" for bugs, we're looking for the radio signal the bug uses to transmit what is heard out through the airwaves to a listener or recorder. We can find that. But there are other bugs that get the "message" out via wire or a laser. These are harder to find. And if someone is outside and pointing a laser at a window to bug a room, you can't find that in a normal sweep. If a small mic and support circuit is hard wired into the area and the wire plumbed outside (really difficult to do), you can't find that in a sweep. Anything that can be kept electromagnetically "quiet" cannot be heard by detectors. The challenges faced by security people are large indeed.

What are the 10 stages in the legendary starfy?

Stages 1-8 are the main game in the legendary starfy Stage 9 is when you play as starfy's sister, starly in pufftop Stage 10 is time based Each Stage consists of 7 levels

Can DVDs be decrypted without leaving a trace on the original disc?

Yes, DVDs are "read only memory" - which means your DVD drive only reads information from the disc (unless you have a DVD burner or "writer," but a burner will only burn to a disc if you specifically request it to.) Bottom line: no matter what you try to do, the disc will not be altered - unless you specifically tell you DVD program to burn to the disc.

What popular things were out when The Beatles were popular?

People mostly remember the days the Beatles were popular for drugs, getting high, and running around shirtless. Other things that were popular during the early days of Beatle popularity are guys with long hair, bell bottom and hip-hugger jeans, tie-dyed shirts, the expression "groovy," Camaros, Mustangs, Corvettes, Firebirds, drive-in restaurants, and drive-in movies.

What are the disadvantages of a refrigerator?

large energy consumptionsome need manually defrosting

encourages buying more food than needed, which increases waste

expensive

takes up room

Why regulator gets shorts?

Regulators gets shorts because it has its own limitations in power. When it overload the shorting starts.

In solar battery charger is it more efficient time to set the solar cell in series or parallel For example if you have 2 of 1.5 V 2500mAh batteries and 5 8V 44 mAh solar cells?

For a very simple circuit, using only the solar cells and batteries and possibly a DC/DC converter to keep the voltage at safe levels for the batteries, placing the solar cells in parallel will yield higher current and shorten the charging time of the batteries. In the example you used by placing the five solar cells in parallel you obtain a theoretical maximum current of 220 mAh. This would bring the charging time to 2500/220 or 11.36 hours. This calculation assumes that for the full duration of charging the current is kept constant at 220 mAh.

What are transformer used for?

Transformers change the numbers of volts, watts, and amperes of the electrical current, from those in the power source to those needed for the mechanism.

Generally, transformers are used to change the input voltage to a desired value of output voltage. Typically, transformers step up (increase) the voltage, or step down (decrease) the voltage. There are many applications and uses for transformers - most of these embed the transformer in another device, so you do not see (or even know about) the transformer.

A computer power supply, for example, has a transformer embedded in it that converts the incoming 120 volts into both 12 and 5 volts. As another example, when travelling from North America to Europe, travelers often take with them an adapter that includes a step-down transformer that converts the European 220 volts into the 120 volts that the North American appliances require. Note that the transformer cannot change the frequency of alternating current, and so some 60 Hz North American appliances will not work properly in Europe, even with a proper step-down transformer, because European power is distributed at 50 Hz. Similarly, some 50 Hz European appliances will not work properly with 60 Hz North America power, even with a proper step-up transformer.

Transformers are also included in adapters for electronics, such as for a cell phone charger. A transformer inside the adapter reduces the incoming 120 volts into a lower voltage (sometimes, 3, 5, 6, 9, 12 or some other value of volts) that the cell phone can accommodate. Such electronic adapters (and the computer power supply, noted in the example above) often include a rectifier that also converts the alternating current (AC) into direct current (DC), which reduces peak-to-peak voltage without affecting RMS (root mean square) voltage.

Most transformers have fixed ratios, meaning the output voltage is always a constant fraction of the input voltage. The output of these fixed ratio transformers will fluctuate in proportion to the fluctuation of the input voltage. Some transformers are variable ratio, meaning you can adjust (either manually or automatically) the ratio of output to input voltages. Automatic variable ratio transformers are typically used to output a constant voltage, regardless of how much the input voltage fluctuates.

Why does the outside temperature not work on a Sharp atomic clock after you changed the battery?

I don't have a "Sharp" brand atomic clock but the one I do have, you need to replace the batteries in both the indoor unit AND the outdoor unit at the same time. Something to do with the proper transmission and receiving of the remote's signal with batteries of equal strength.

How do rechargeable batteries work?

Click the link below

A rechargeable battery is also known as an accumulator. It uses one or more electrochemical cells. During the charging process the cathode end which is the positive has negative electrons pushed through it mixing in the small chamber of the battery. The anode has positive electrons come in. The positive and negative electrons are combined and mixed inside and are released from metal to metal contact and are then used as electricity.

What are some consequences of hacking?

being jailed

need to pay a fine

lose you're rights to use a computer

Answer

In my opinion hacking is gaining access to a system and its servers or banks of information. There are are two types of hacking illegal and legal. Illegal is when you hack without a person's permission. Legal hacking is obtaining a person systems legally. The consequences of illegal hacking are thousands of dollars in fines, imprisonment, and the seizure of your computer.

Answer

Hacking is to know and understand how systems work. Cracking is doing harm with theses skills.

If searching for consequences of cracking then: Well, when detected... : probably, the crackers IP-adress is going to be traced and disabled acces to internet for a while. Than, when the cracking was real seriously, (like cracking government systems and such) the crackers PC, and thus the crackers location is located, and the cracker gets caught.

Answer

In Pennsylvania hacking is illegal. Hacking is known as "unlawful use of computer and other computer crimes - 18 Pa. Cons. Stat. § 7611" which is a third degree felony. Use of force for the protection of property - 18 Pa. Cons. Stat. § 507(c)Limitations on justifiable use of force (4)(ii)(B) such force is necessary to prevent the commission of a felony in the dwelling. What do you think the consequence of hacking illegally into my computer is, let's hope it is an arrest.

How do you make a nine volt battery?

Arrange the four 1.5volts cells elongated in a line and connect the wires one from negative and the other from positive and to check attach it with a bulb or a toy car

Who was the inventor of the microscope?

The original inventor is not easy to identify. An early microscope was made in 1590 in Middelburg, Netherlands.

Two eyeglass makers are variously given credit:

Hans Lippershey and Hans Janssen.

Note also that Giovanni Faber coined the name microscopefor Galileo Galilei's compound microscope in 1625.

How much voltage inside a sunbeam battery?

Automobile battery is 12 volts. If it is fully charged you should actually read 12.6 volts.
