Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
What is the difference between output and input?If you sing into a microphone you can hear the microphone's output.Sound coming out of the power amp to the speakers.That is the input of the loudspeaker.Do you see the difference?Your voice is the microphone's input. Its output is electrical impulses that are input to the amplifier. The amplified impulses are the output of the amplifier and input to the speaker. Sound waves are output of the speaker and input to your ears.
Efficiency = Output/Input. This is usually expressed as a percentage but may be given in the form of a ratio.Another AnswerEfficiency is output power divided by input power, normally expressed as a percentage.
Power input = 700 WEfficiency = 75% so power output = 75% of 700 = 525 W Time = 30 seconds => Work done = 525W * 30s = 15750 W.s = 15750 Joules = 15.75 kiloJoules.
Generally efficiency is the ratio of the energy or power utilized usefully to the energy or power given as input to the device. So efficiency in this case = 50/75 = 2/3 Usually efficiency will be given in percentage. So multiplying 2/3 by 100 we get 66.7% as the efficiency of the machine.

B.) efficiency
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
If the output power is 70% of the input power, then the output is roughly 1.55 dB downcompared to the input.If the voltage at any point of the output waveform is 70% of the voltage at the same pointon the input waveform, and the input and output impedance are equal, then the output is3.1 dB down (rounded) compared to the input.
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
This is called the efficiency of the power plant. Efficiency is a measure of how well a power plant can convert its fuel input into useful electricity output.
Output Power divided by Power Factor.
UPS is Uninterruptable Power Supply. It is neither input not output. It supplies electrical power to a computer when the main electrical supply is interrupted. It does not handle data in any way.
Output - because it is outputting power to the rest of the device
power in, and power out--input and output.
input 220v ac & output 24v dc
Output power can never be more than input power. With a transformer, it is possible to increase the output current (while decreasing the output voltage), or to decrease the output current (while increasing the output voltage).
