How does force affect power output?
Force affects the speed of power output. If the driving force is slow, the speed of power output will also be sluggish. Alternatively, if the driving force is fast, power output will be able to match the speed.
How do you calculate the power output with a changing frequency?
Frequency has no effect on power output. Impedance, Voltage, and Current all affect Power (watts).Use the following formula(s) to calculate power:E^2/R R*I^2 E*IFor more information study Ohm's Law.AnswerThe power of an a.c. load is given by P = U I x (power factor). Power factor is the ratio between resistance and impedance. Impedance is the vector sum of resistance and reactance. And reactance is affected by frequency. So, yes, frequency does affect the power of a load. To calculate the power for different frequencies, just work through the factors listed in the preceding sentences.
What must you know in order to calculate a machine's efficiency?
The efficiency tells you how good the machine is. Efficiency equals the power output of the machine divided by the power that is input via a shaft, or via electrical wires, or via fuel. So if the machine has a low efficiency it wastes power and energy, which costs money. The average ordinary automobile has an efficiency of 20-25%. A lot of research work goes into improving that figure.
How is energy efficiency determined?
You divide useful output energy by the input energy. Or equivalently, useful output power by input power.

What does one calculate dB power?
This calculation will give you the ratio, in decibels, between two power values. For example, you can calculate the difference in dB between two amplifiers with different power output specifications calculate in dB Power Ratio.
How to calculate amp load for a generator?
Take the power output of the generator and divide it by the voltage output. I = W/E.
How the efficiency of machine be obtained?
Efficiency is output power divided by input power. You somehow have to measure, calculate, or estimate both; the details will vary depending on the type of energy input and energy output.
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 mechanical output power while lifting a 300 gram mass 60 centimeters?
Not enough information. You can calculate the work (using the formula for potential energy), but to calculate the power, you would also need the time (how fast is this done?)
Can we improve generator power factor for increasing active power?
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
