What is the maximum input voltage that could be used to ensure linear operation of the inverting and noninverting amplifier?

A: Linear operation has nothing to do with voltage. It is a function of voltage vs current at a particular load. Most transistors have a very linear parameters at low current but at hi current the linearity changes and for some transistor drastically. So choosing a transistor for amplification is different then from choosing for a switch application.

The gain of an operational amplifier will be maximum?
A: the gain will be maximum at the open loop configuration and decrease as frequency increases
Will 8 ohm speaker work with 4 ohm bass guitar amplifier?
Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.
How does a transistor act as a oscillator?
A: actually any active components will oscillate with positive feedback A transistor can be used as an amplifier along with an LC tank circuit to form an oscillator; it is an active device (as LIBURNO states) which will amplify the feedback signal coming out of the LC tank circuit. The tank circuit has a natural resonant frequency, meaning the L and C together will try to generate a specific frequency; this is then fed back into the input of the transistor amplifier, and the output is fed to the LC tank circuit exacerbating this oscillation until it reaches its' maximum level. An inverting amplifier can be used similarly; the output is fed to the input; this will cause the output to change as fast as the amplifier can. The frequency of this design is much harder to control, but potentially higher. Also, without the LC tank, the output voltage will remain lower.
How do you install a linear CB amplifier?
You don't. Linear amplifiers are illegal for CB use. The maximum input into the final stage of a CB transmitter is 5 watts.
Does Maximum manpower requirements for power production exist during the longer term operation and maintenance?
True!

A: the gain will be maximum at the open loop configuration and decrease as frequency increases
In which amplifier occurs Maximum distortion?
CLASS -C amplifier is having high ditortion due to which they are not used in audio frequency work
Why neutralisation is used in tuned amplifier?
neutralization is one of the methods to make the amplifier unilateral i.e. to remove internal feedback of the amplifier. It is done to obtain the maximum gain from an amplifier.
Will a 1200 watt amplifier blow out a 1000 watt subwoofer?
Technically, yes. Practically, no. Amplifiers and speakers are rated by the maximum amount of power (and at what impedance) they can handle. A 1200 watt amplifier will eventually destroy a 1000 watt speaker if it is operated at maximum power. In normal use, however, you rarely even get close to maximum rating.

Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.

What is the maximum tv cable length with the use of a inline amplifier?
100m max DO NOT surpass this at all cost. We could all die.

Is there possible the transformer can operate below the rated voltage?
A: Transformers are designed for the maximum voltage they can sustain in operation a lower voltage operation should not bother them
What is the maximum range for voice messages when the transmitting range of a sincgars rt-1523 and the radio is mounted in a vehicle with a power amplifier?
The running range of a RT-1523 in manpack mode is about 8KM. The running range of a RT-1523 in vehicular made using a power amplifier is about 35KM. There is no maximum range due to being able to use other systems as retrans stations.

Can you use paperjam guitar without amp?
yes, you may use it without the amplifier...all it does is make the guitar louder than the maximum volume.
