The copper loss is directly proportional to the square of current flowing through the winding, and is also known as I2R loss or ohmic loss. The copper losses occur due to current flowing through the windings. And if both objects have different polarities, objects attract each other.Īccording to coulomb’s law, the equation of electric field is Īccording to gauss’s law, the equation of electric flux is If both objects have the same polarity, objects repel each other.
When a charged object enters the electric field of another charged object, it experiences a force as per Coulomb’s law.Īs shown in the above figure, a positively charged object is placed in space. One coulomb is defined as the quantity of charge transferred in one second.Īn electric field is a field or space around an electrically charged object where any other electrically charged object will experience a force.Īn electric field is also known as electric field intensity or electric field strength, denoted by E.Įlectric field is defined as a ratio of electrical force per test charge.įor parallel plate capacitor, the voltage difference between two plates is expressed a work done on a test charge Q to move from the positive plate to negative plate. When any matter is placed in an electromagnetic field, it will experience a force.Įlectric charges can be positive (proton) and negative (electron), measured in coulomb and denoted as Q. The inductance is defined by a ratio of magnetic flux linkage (ф B), and the current passes through the inductor (I).Įlectric charge is a physical property of substance. Sometimes, an inductor is also known as coil, reactor, or chokes. The capacitance depends on the distance between two plates (d), area of plate (A), and permittivity of dielectric material.Īn inductor stores electrical energy in the form of a magnetic field when electric current flows through it. The electric charge Q accumulated in capacitor is directly proportional to the voltage developed across the capacitor. The effect of capacitors in electrical circuits is known as capacitance. It is defined as a ratio of velocity and frequency for sinusoidal waves.Ī capacitor stores electrical energy in an electric field when voltage is supplied. Wavelength is defined as a distance between consecutive corresponding points (two adjacent crests, or zero crossing). The frequency is inversely proportional to time period (T).
The time period is defined as the time required to produce one complete waveform cycle, denoted as T. Generally, the frequency is 50 Hz or 60 Hz. One hertz is equal to one cycle per second. It is denoted as f and measured in Hertz (Hz). Frequencyįrequency is defined as the number of cycles per unit time. When the load is resistive, power factor is near to 1 and when the load is reactive, power factor is near to -1. , which use specific parameters for that kinds of exponential behavior.The power factor dimensions less number in the closed interval of -1 to 1. The parameter \(k\) will be zero only if \(y_1 = y_2\) (the two points have the same height).įor specific exponential behaviors you can check our Indeed, if the parameter \(k\) is positive, then we have exponential growth, but if the parameter \(k\) is negative, then we have exponential decay. Indeed, by dividing both sides of the equations: Solving this system for \(A_0\) and \(k\) will lead to a unique solution, provided that \(t_1 = \not t_2\). Technically, in order to find the parameters you need to solve the following system of equations: So that this function passes through the given points \((t_1, y_1)\) and \((t_2, y_2)\).īut, how do you find an exponential function from points? The idea of this calculator is to estimate the parameters \(A_0\) and \(k\) for the function \(f(t)\) defined as: Exponential Function Calculator from Two Points
