Where does the energy come from to amplify the signal in a amplifier?

The energy comes from an additional power source, like a battery. Via various resistors and capacitors, the energy from the power source is put into the circuit. The signal that enters the ciruit will exit the circuit with a higher energy; the signal has been amplified.

Can you amplify the electricity when you have only very small power supply or any mechanism for it?
you really can't amplify electricity. You can amplify sound but that is different. You can change the voltage but the actual power will not change because as voltage is raised current is reduced. you can only increase power by increasing the mechanical input to a generator which will increase the electrical power as well. The conservation on energy says that power cannot just be created. It needs to come from some where either mechanical or thermal. Following the conservation of energy, you can convert kinetic energy into electric energy using a (relatively) small amount of electricity - this is what a synchronous generator does. A small amount of electricity is used to create a magnetic field; the stronger this field, the more energy can be "pushed out" of the generator; this energy must come from the kinetic energy stored in the spinning machine. In this way, a synchronous generator can be thought of as an electricity "amplifier".
Why is gain affected when the bypass capacitor is open?
Applied input signal at the base of the amplifier appears across the emitter resistor (RE) due to inter electrode capacitance so it should be bypassed the emitter resistor (RE) through the bypass capacitor (CB). unbypassed signal will be amplified (common emitter amplifier) and reverse back from the emitter to the collector through the base, amplified signal from the emitter to the collector (common emitter amplifier) is 1800 out of phase to the amplified signal from the base to the collector (common base amplifier), so reduced the gain.
What is the time for the TV signal to come from the TV mast to your TV set?
The signal will move down the cable at from about 1/3 the speed of light to about 9/10 the speed of light, depending on the type of cable used. If there is a booster amplifier in the cable between the antenna and the TV set this will add more delay. You will need to know the length and types of cable used (and look up their signal propagation speed) as well as the delay of your booster amplifier if your system has one to calculate the answer to your question.
Car Audio Amplified?
A car audio system is nothing without its amplification device. It’s the heart and soul of the car audio world. It’s what makes everything go, so adding a good car amplifier to your sound system is a crucial component of the car audio purchasing process. The reason the amplifier is so crucial is because the amplifier is what gives the speakers their power. The bigger the amplifier, the louder the speakers can be. The amplifier takes the sound signal that’s being generated by the head unit and boosts it before sending that signal to the speakers. It’s essential that you find the right amplifier for your car stereo system. Yes, you can overdo it, so make sure you realize what you’re working with. It’s likely that you’ll want to upgrade your speakers before adding an amplifier, because you can completely blow them out if you’re not careful. Amplifiers are measured by how many watts they produce, and the wattage can range anywhere from 40 to 1,500 watts or more. Obviously, the higher-watt amplifiers are going to come with a higher price tag as well as the added signal boost that you’ll get from the increased power. Make sure you budget properly, because the top-of-the-line amps can run you $500 or more. Another thing you’ll want to consider when looking for an amplifier is the size. Amplifiers come in many different shapes and sizes. You’ll want to measure the space you have in your trunk or wherever you plan to place the amplifier before you purchase it. You don’t want to purchase an amplifier that is too big for the allotted space. All factors considered, adding an amplifier is going to give your car audio system a huge boost. Depending on the amplifier you add, people should definitely be able to hear you coming, no matter what kind of car you drive.
Where can one learn how to use a video distribution amplifier?
One can learn how to use a video distribution amplifier by reading the guides that come with these products. One can also watch video tutorials on YouTube.

How can you tell if your 2004 Chevy Trailblazer has a factory amplifier or not?
If it says BOSE on it anywhere it will have an amp for each speaker in the doors. The Factory GM radio does not have an amp and has poor sound to amplify. Most members of our forum choose and after market stereo to amplify. Come and read in our AUDIO section www.trailvoy.com

Does the factory CD player for a 2007 Suzuki Forenza come with right and left audio outputs?
To my knowledge, no. I have an 07 Forenza and have signal routed to my amplifier from rear door speakers themselves filtered through a signal suppressor.
Where does all energy ultimately come from?
the motion energy comes from the signal of your brain which then transerfs that to the object you move

How intercom system works in general?
humans hear sounds beetwen 300herz-3.4kherz ;at this system we need to send a signal to the first spkear this signal passing the amplifier and then come to the spekar which is at the out of the circuit ;but coupling capasitör and resistörs and transistörs are important for good sound

Does a 2000 Chevrolet Malibu come with a factory amplifier for the sound system?
This does come with a factory amplifier for the sound system. Sometimes it comes disconnected and needs to be reattached.
Do you need a amplifier for a DJ set?
You DO NOT need an amplifier for a dj setup. Some speakers now come with a built in amp, known as a "POWERED SPEAKER".
How does a satellite dish works?
The satellite dish is picking up weak signals from around, and center them onto its "burn point", in which all the signals are concentrated, thus strengthened. Answer2: The satellite dish is a parabolic shape. The parabola collects signals that come into the dish and directs them to the focal point. At the focal point an electronic amplifier is located to pickup and amplify the signals.
