What is the relationship between energy input energy output and energy losses whenever transfer of energy takes place?
Energy input = energy output + losses. Both energy output and losses are usually positive (they might also be zero in some specific cases), meaning that (usually) each of them individually is less than the energy input.
Why CB amplifier preferred for high frequency than CE amplifier?
1)in cc configuration we use to get the low output impedence where as in ce we use to get the high output impedence. 2)in cc amplifier we use to have the voltage gain equal to unity where as in ce amplifier we use to have the high voltage gain. 3)in cc amplifier there is high power gai which is used for impedence matching where as in ce amplifier due to the high voltage gain the impedence matching is less impossible.
In a real machine why is the work output always less than the work input?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
Why out put current increase in transformer with capacitance load?
ferranti effect...B.*If we use capacitive load the stator MMF aid the rotor MMF. It means that in times of capacitive load rotor flux and main field flux are additive. So the alternator voltage increase with capacitance loading.[By Akhtaruzzaman08]
Why ce configuration amplifier is commonly used?
generally CE amplifier is considered as the most common amplifier because of two reasons :-1. it has a good current gain (almost >100) :- this is eslf -explainable as more the output more willingly it would be used as an amplifier2. low input current :- this is the most important reason , if we recall the input current in CE configuration we will come to know that it is the base current . base current has less magnitude this helps the designer to control it easily when compared to higher order magnitude currents like collector and emitter current as
When is mechanical advantage less than 1?
When the output is less than the input. Mechanical advantage is expressed as the ratio of the output to the input.
What is the output and input forces?
An output force is the force that is exerted from the input force to create motion of the resisting object. the input force can be less or more then the output force
What is input and output force?
An output force is the force that is exerted from the input force to create motion of the resisting object. the input force can be less or more then the output force
What is a current amplifier?
A current amplifier this a device which heightens the current of the input signal at its output. If we are speaking of semiconductor devices i.e. transistors, than this form of amplification is done so by applying input signal the the base of the transistor, and drawing the output singal from the emitter. This amplifier can also me called an emitter follower. A current amplifier will only yield a gain of less than 1, but the current can be amplified up to 10x the input current.
What stronger work output or work input?
In theory, work output might be equal to work input; that would be 100% efficiency. In practice, the output of a machine will be less than the input; i.e., some energy will be lost.In theory, work output might be equal to work input; that would be 100% efficiency.

Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
Why is the work output of a machine always less than the work input?
In a real machine, the output work is always less because input energy will be converted to heat energy and lost.
Why common emitter configuration is mostly used for transistor as switch?
because in ce configuration value of input voltage requried to make the transistor on is very less value of the output voltage or output current
Is work output greater than work input?
No. Work output is less than or equal to work input. Since some energy (work) is lost in most processes, it will usually be less.
If you double the input of a function and it results in half the output and if you triple the input and it results in a third of the output what can be guessed about the function?
~the function is most likely inversely proportional. ~more input results in less output.
If you quadruple the input of a function and the resulting output is one-fourth the original output what may be true of the function?
More input results in less output. The function is inversely proportional.
Why is always work output less than work input?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.
