This equation is based on the Sine function
Let w = 2 Pi f
The basic V I equation for an inductor is
V(t) = L d/dt I(t)
Now
I(t) = A Sin(w t)
V(t) = L d/dt I(t)
V(t) = L A w Cos(w t)
Z = Vrms / Irms
Now
Vrms = A L w /Sqrt(2)
Irms = A/Sqrt(2)
Therefore
Z = Vrms / Irms
( A L w /Sqrt(2))

What statement best describes deductive reasoning?
moving from general conclusions to specific observations
How does a mathematical model help you understand the concepts of science?
because a model shows an equation that relates to the model there for to get a better understanding Any model models the relationships that you want to show. A mathematical model represents something, such as one or more concepts of science.
What is Balanced equation for what happens when limestone is heated?
CaCo3+O2 -----> CaO2 + CO2 ************************** 2nd Opinion: Close, but no cigar. What you want is CaCO3 -----> CaO + CO2
How do you remember the photosynthesis equation?
The equation for respiration is:C6H12O6 + O2 --ENZYMES--> CO2 + H2O + 36ATPORSugar + Oxygen --ENZYMES--> Carbon Dioxide + Water + EnergyAerobic respiration, the production of energy with oxygen, is the opposite of photosynthesis: the reactants are the products of the other.If you want an easier one though, one that they teach in middle school, it is just:C6H12O6 + 6O2 ---> 6CO2 + 6H2O + E (energy)Or - glucose + oxygen ----> carbon dioxide + water + energy
How do you convert inches to centimeters to the nearest 0001 of a centimeter?
An inch is equivalent to 2.54 centimeters. Having said that, if you take the formula C= x * 2.54 (x being inches and C being centimeters you will get your answer) Just plug in the inches you want to convert to centimeters into the equation in the place of x and solve the equation you will be able to calculate the conversion.
Describe in brief the type of power factor improvement system?
You want a power factor of 1 or 100%, which is a purely resistive circuit. If you have a motor or some other inductive load in a circuit the total voltage and total current in the circuit will not be in phase (phase shift), your power factor will be less than 1. By adding a capacitor (180 degrees out of phase with inductive load) to the circuit that has a capacitive reactance equal to the inductive reactance of the motor, you can cancel the phase shift and have an ideal power factor (no wasted power). Anything above .9 would be good.
In capacitive reactance how its formula can be determined in easy way. please answer?
The formula is 1/(j*w*C), where j is an imaginary number (this makes it reactance, not resistance), w is the frequency in radians, C is the capacitance. If you want a proof of this, you should look at wikipedia under laplace transform. I'm sorry, the proof of this is probably not what you would consider simple or easy, if this is what you're looking for. It is based on calculus, and I know of no way to get around it.

In transformer if frequency are reduce then what happen?
t's basically a matter of the magnetizing inductive reactance which is inversely proportional to frequency. You want to keep the magnetizing current low to minimize power loss and avoid saturating the core. The higher the frequency, the lower the required inductance for a given inductive reactance and magnetizing current, thus the smaller the required core and/or number of turns on the windings.Magnetizing current is a normal parasitic byproduct of the transformer inductance and the applied voltage level and frequency. The amount of power that can be transferred through a transformer is usually limited by the transformer winding resistances and is unrelated to the magnetizing current. Thus core size goes up at higher power levels due to larger required wire size, not due to any core limitations.

You can if you want to
Why would you want to simplify an algebraic equation?
Simplifying an equation often helps solve it.
Why is knowing how to write an equation of a line important?
Because if you ever want to graph that equation you need the actual equation itself to help you graph it.
