The POWER function returns a number raised to a given power. POWER is an alternative to the exponent operator (^) in a math equation.. The POWER function takes two arguments: number and power.Number should be a numeric value, provided as a hardcoded constant or as a cell reference. The power argument functions as the exponent, indicating the power to which …
If the calculated power is positive, (+P) in value for any formula the component absorbs the power, that is it is consuming or using power. But if the calculated power is negative, (–P) in value the component produces or generates power, in other words it is a source of electrical power such as batteries and generators.

Learn the Power Formula. We've seen the formula for determining the power in an electric circuit: by multiplying the voltage in "volts" by the current in "amps" we arrive at an answer in "watts." Let's apply this to a circuit example: How to Use Ohm's Law to Determine Current. In the above circuit, we know we have a battery voltage of 18 volts and a lamp resistance of 3 Ω.

The subscripts 2 and 1 indicate the final and initial velocity, respectively. This theorem was proposed and successfully tested by James Joule, shown in Figure 9.2.. Does the name Joule sound familiar? The joule (J) is the metric unit of measurement for both work and energy. The measurement of work and energy with the same unit reinforces the idea that work and energy …
Find power factor from the formula power factor = P / S. Find the angle cos⁻¹(power factor) and draw a power triangle. Calculate reactive power Q from Pythagorean theorem: Q = √(S² - P²). Correct the power factor by adding a capacitor or inductor, the size of which will balance the calculated reactive power.

Where V and I are the sinusoids rms values, and θ (Theta) is the phase angle between the voltage and the current. The units of power are in watts (W). The dissipated power in AC circuits can also be found from the impedance, (Z) of the circuit using the voltage, V rms or the current, I rms flowing through the circuit as shown.. Tutorial Example No1
Power is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation. Power = Work / time or P = W / t . The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time.
It is common to call "design" the election of the sizes of the parts of hydrocyclones chosen from those provided by the manufacturers. It is really a geometric selection for which empirical formulas exist (see Chap. 9).In this chapter we will develop a design for hydrocyclones as a mixed-flow turbo machine including different inlet, vortex and apex geometry choices …
Remember that V p, I p, V L, and I L are all rms values and that θ is the angle of the load impedance or the angle between the phase voltage and the phase current.. A second major advantage of three-phase systems for power distribution is that the three-phase system uses a lesser amount of wire than the single-phase system for the same line voltage V L and the …

Note that this equation for the time-averaged power of a sinusoidal mechanical wave shows that the power is proportional to the square of the amplitude of the wave and to the square of the angular frequency of the wave. Recall that the angular frequency is equal to (omega) = 2(pi)f, so the power of a mechanical wave is equal to the square ...

The power set is a set which includes all the subsets including the empty set and the original set itself. It is usually denoted by P. Power set is a type of sets, whose cardinality depends on the number of subsets formed for a given set. If set A = {x, y, z} is a set, then all its subsets {x}, {y}, {z}, {x, y}, {y, z}, {x, z}, {x, y, z} and {} are the elements of power set, such as:
