What will happen if instead of npn transister pnp is used?

It really depends on the configuration of the circuit. A transistor can be connected in any of at least 3 configurations: common base, common emitter, and common collector. Each of these type of configurations determines where the source of electron flow is connected. After that, the biasing configuration needs to be determined, and this will change depending on whether you are using an NPN or PNP transistor. In the simpler biasing configurations, swapping a NPN for a PNP or vice versa will prevent current from flowing as the collector, base, and/or emitter will be reverse or forward-biased incorrectly. You would then either be blocking currently flow, or possibly causing a short circuit. Again, it depends on the configuration. Generally speaking, it is not a good idea. One potential result is you can damage the transistor or even destroy it or possibly damage other components in the circuit.

Can electronics start to ruin your brain?

It really depends cell phones can give brain tumors if you talk to long but normal phones don't. It's because of the radiation they also can cause brain cancer. (fyi changing ears every once in a while when you talk on a phone will lower the chance of a brain tumor or brain cancer)

Yes it does, especially if you keep it in your pockets it'll kill your sperm cells or egg cells. if you keep it in your shirt-pocket it can give you a different type of cancer.

My SD card is plugged into my computer but my files won't open up why?

Perhaps you have the new High Density SD card (it will say HD on it if so)

A LOT of old card readers cant read that type of card.

Best solution is to buy a new card reader or alternativly use the camera cable.. (assuming its a camera). Another solution is to reinstall the car reader software or to download Gpartet and reformat the Sd card.

Can you connect a reverb along with a surround sound?

You cannot add an external reverb to a surround sound (Dolby Digital or DTS) signal connected through the digital input, such as a DVD player. Many receivers can add reverb and ambient echo to the sound themselves to emulate different venues. If you want reverb for your voice for karaoke, you can do this inside the DVD player or by adding an external reverb processor that adds effects to the microphone cable signal.

What is multiplexing why is multiplexing needed in electronics communication?

multiplexing refeers to the transmission of different signals in the same channel simultaneously. There are many forms of multiplexing that can be used, including frequency division multiplexing(FDM) where individual signals are transmitted over adjacent , non overlapping frequency bands. they are transmitted in parallel and simultaneously in time. In time division multiplexing(TDM) each signal is allowd to use the whole bandwidth for a certain period of time. Multiplexing is needed so that the available channel can be used efficiently and also to save costs. There is too much to know about multiplexing, here is just a short overview. One thing that one has to know is multiple access.

Can you use an unlocked android phone without a carrier?

You can not make phone calls without a carrier. You could theoretically make skype calls if it has Wi-Fi.

How does a mono amp work?

A mono amp, is half of a stereo amp.

It has one input and one output.

Tell about the need for and use of test equipment in electronics?

without any test equipment , u cannot take out the exact readings of the gadget , and u cannot find out the real problem with the gadget , they r used to detect where the main problem arises in the gadget , which all parts r correct by comparing there values with correct parts , and where the main problem arises.

What is the use of crystal detector in electronics?

A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.

Where can you obtain a Denon AVR 2400 receiver manual?

A website is listed in the Related Links below with a scanned copy of the manual.

How long will a 1000VA inverter provides backup power with 100 Amps Battery for 3 fans 3 lights and 1 tv?

The running time depends on two things: the actual power the inverter can supply, and the actual power drain of the loads.

A 1000 VA inverter may be able to supply 1000 VA, but it battery size determines *how long* it can supply power for. A 100 amp battery can probably supply 10 amps for 10 hours (100 amp-hours), but it may only supply 100 amps for perhaps 45 minutes - if it does not overheat! Generally, batteries give less effective power at higher power drain.

You also need to know how efficient your inverter is - it may be 90%-plus, it may be as bad as 75% or less.

So you will need to (1) find out how much power your appliances draw (let's say its 300 watts), then (2) examine the specifications for the inverter-battery combination to discover how long they can support your power drain.

Be aware that 300 watts load is over 25 amps current drain at 12 volts, so you are already getting away from the 100 amp rating, to a lower value due to the high power drain on the battery.

Expressed in scientific notation 0.0930 m is?

Expressed in scientific notation 0.0930 m is: 9.3 × 10-2 m

What is Contact block 1N.O. 1N.C. 1N.O. scaled?

It is a contact block with three poles. Pole one is normally open, pole two is normally closed and pole three is normally open. These reading are taken in a de-energized condition. When energized the contacts will change status to closed, open and closed.

What a need for analyzing transistor circuits using different parameter?

At different parameters the input and output relation differs ,amplification factor varies across the various configuration of transistor. To know how to use the transistor weather as a switch or as an amplifiers analyzing it across all the parameters is important.

How much money is a computer?

All computers are different prices. The price of a computer mainly depends on what company you buy one from.

What are the tools and equipment use in electronics?

There are myriads of meters components to do measurements the basic is the oscilloscope and multimeter.

Where is electronic control module on 1994 ford escort?

It should be attached to the side of the distributor. It requires a special wrench($ 9.00) to remove and install the new one.
