Why input current of USis less than Output current?
The input voltage to a rectifier is less than the output voltage because the rectification process involves converting alternating current (AC) to direct current (DC), which typically has a peak voltage that can exceed the RMS (root mean square) value of the AC input. Additionally, during rectification, voltage drops occur across the diodes or other components, which can further reduce the effective input voltage. As a result, while the output voltage can be higher momentarily, the overall conversion and losses lead to a lower input voltage compared to the peak output voltage in a rectified waveform.
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.
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.
The common base configuration is not suitable for current amplification primarily because it has a low input impedance and high output impedance, which limits its ability to deliver significant current gain. This configuration typically provides voltage gain but does not amplify current effectively, making it less ideal for applications requiring substantial current amplification. Additionally, the input signal must be applied to the emitter, which can make it less convenient for many circuit designs compared to common emitter or common collector configurations.
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.
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

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.
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.

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
~the function is most likely inversely proportional. ~more input results in less output.
More input results in less output. The function is inversely proportional.
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.
True ~ LiL' Diablo
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.
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.
