What should radio transmissions be limited to?
The minimum amount of power necessary to carry out the desired communication.
What does effectivness mean?
Efficacy is the capacity (or the power) to produce an effect or to achieve a desired result.
What does efficacous mean?
able to effect something: having the power to produce a desired result, especially an improvement
How the capacitor valve calculate for a for a load?
I assume that you are asking how to calculate the 'value' of a capacitor? Well, it depends what it is used for. If, for example, it is used to improve the power factor of a load, then it is first necessary to determine what the load's existing reactive power is; then, you need to know what reactive power is necessary with the power factor at its desired value; finally you need to difference between the actual and the desired values of reactive power -and this will be the necessary value for the capacitor. Power factor correction capacitors are rated in reactive volt amperes, not farads.
What is logarithm?
a quantity representing the power to which a fixed number (the base) must be raised to produce a given number.
What is zero to the power of a number equal?
Zero to the power of anything is undefined. There is no number of zeros multiplied together that can produce any number other than zero, so zero to the nth power is undefined, by definition.
How do you calculate capacitor rating for improving power factor?
Power-factor capacitors are rated in reactive volt amperes. To determine the appropriate rating, it is necessary to determine the existing (inductive) reactive power of the load, then determine the amount of (capacitive) reactive power necessary to achieve the desired power factor (it's rarely economical to try and achieve unity power factor), and this will be the necessary reactive power of the capacitor bank.The capacitance of power-factor correction capacitors is not really relevant to the calculation, which is why they are rated in reactive volt amperes, rather than in farads.
What is the difference between Efficiency and Coefficient of Performance?
efficiency is capacity of engine to produce power from fuel supplied while cop is how effectively energy is used to obtain the desired effect
How does voltage remains constant in resistors connected in parallel?
It is not necessary for anything about them to be the same.All that is necessary is that they create the desired equivalent resistor, having the correct resistance and power dissipation rating without overstressing either resistor.
What function do mitochondria?
It act as a powerhouse.They produce ATP in the cell. ATP store the energy and release when necessary
Why do most very small engines operate on a two-stroke cycle?
two-stroke engines can produce more power than four-stroke engines that have the same size. they can occupy small spaces and produce the desired power. they are on the other hand produce more pollution than 4-stroke engines. that's why they are limited or suitable for small engine spaced machines
How can the power of the sun be converted?
Photo-voltaic cells absorb solar radiation energy and produce direct current output. A number of these cells arranged as an array can produce a useful amount of electric power.
