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]
what are a few of the disadvantages to a brush-less motor controller?
The brush-less motor controller has a smaller output current than one DC motor. The brushless also has less of a output voltage. The maximum output voltage is 50V, where a regular DC motor would have a maximum of atleast 60V.
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 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 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
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.
If the output force is less than the input force of a simple machine the mechanical advantage is less than one.?
True ~ LiL' Diablo
Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes, it is true. Due to factors such as friction, heat generation, and other inefficiencies in the machine, some of the input energy is always lost to the surroundings rather than being converted into useful work output, resulting in the work output being less than the work input.
How does the output work compare to the input work for a machine that has an efficiency less than 100?
For a machine with efficiency less than 100%, the output work will always be less than the input work. This is because some of the input work is lost as waste energy due to factors like friction, heat, or other inefficiencies in the machine. The efficiency of a machine is a measure of how well it converts input work into useful output work.
Why is the work output of a machine always less than the work input?
The work output of a machine is always less than the work input due to energy losses in the form of heat, friction, and other inefficiencies. These losses result in some of the input work being converted into forms other than useful output work, leading to a decrease in efficiency.
