You divide useful output energy by the input energy. Or equivalently, useful output power by input power.
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).
The efficiency is output divided by input.
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.
Efficiency is output power divide by input power.
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.
