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*I
For 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.Wiki User

∙ 10y agoCan't be done. Power is the product of voltage and current...frequency has nothing to do with it.

Definition of half-power frequency?
The frequency on an amplifier response curve which is greater than the frequency for peak response and at which the output voltage is 1/√2 (that is, 0.707) of its midband or other reference value.
How do you calculate output power?
power=work/time=fd/t=watt This is how you would figure out your power or wattage. i hope i could be of help to you!
How do I calibrate a frequency converter?
To calibrate a frequency converter, first, ensure that all power connections are secure and proper safety precautions are taken. Then, use a multimeter to measure the output frequency of the converter. Adjust the calibration settings on the converter until the measured frequency matches the desired frequency. Finally, verify the calibration by testing the converter with different loads and checking if the output frequency remains stable.

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 does a frequency inverter work?
A frequency converter converts alternating current of one frequency to alternating current of another frequency. Generally it's used for controlling the ac motor speed by changing the supply frequency.

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 the output of transmitter?
The output of a radio transmitter is ac power at a radio frequency, designed to run into a load with a specified resistance, often 50 ohms.
Why cut off frequency is called half power frequency?
Cut off frequency is that frequency at which the power output of the circuit reduces to half of its power in pass band. Power (P)= Current2 X Resistance. so to reduce the power by half we need to reduce the current by 1/sqrt{2} = 0.707 = 3 db. So it's also called half power frequency. http://enter4joy.com
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.
Definition of half-power frequency?
The frequency on an amplifier response curve which is greater than the frequency for peak response and at which the output voltage is 1/√2 (that is, 0.707) of its midband or other reference value.
