What else can I help you with?
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
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 input and output?
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 can be express mathematically as?
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.
An electric drill has an efficiency of 75 percent. If the motor has a power input of 700 watts and is run for 30 seconds. How much actual work is done. How would I get a kilojoules answer?
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.
What does 35 percent efficient mean?
A system that is 35 percent efficient converts 35 percent of the input energy into useful work or output, while the remaining 65 percent is lost, often as waste heat or through other inefficiencies. For instance, in an engine, if it burns fuel to produce power, a 35 percent efficiency means that only 35 percent of the fuel's energy is effectively used for propulsion, with the rest wasted. This efficiency rating helps gauge performance and indicates potential areas for improvement.
The ratio of output to input power in percent is called?
effciency
The ratio of output power to input power in percent is called a conductivity b efficiency c work d horsepower?
B.) efficiency
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
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.
Another way of saying that the output is 70 percent of the signal input at cutoff frequency is that the output is up or down dB at frequency cutoff?
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.
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
If 35 percent of the fuel is converted into electricity this is called the what of the power plant?
It is the efficiency of the power plant.
How does the power input affect the temperature output in a thermal system?
The power input in a thermal system directly affects the temperature output. Higher power input typically results in higher temperature output, while lower power input leads to lower temperature output. This relationship is governed by the laws of thermodynamics.
How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
Is ups input or output device?
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.
Is power supply input or output devices?
Output - because it is outputting power to the rest of the device
What does the power relatio0nship state on a transformer?
power in, and power out--input and output.
What is the required input and output voltages for a personal computer to power on?
input 220v ac & output 24v dc
