Problem2:If the current and voltage of an electric circuit are 3 A and 15 V respectively. Calculate the electrical power. Solution: Given I = 3 a and V = 15 V Since P =VI = 3 x 15 We get, P = 45 W Problem3-If the mass of a person climbing a tree which is 5 meters high...
As can be seen in the above equation, the reference of the reactive power appears which is normally set at zero so that the current is being injected into the public grid with unity power factor. There is another type of wind energy extraction system where the objective is to compensate the...
> Voltage > Current > Power > Energy • All the metals contain a large number of free electrons which move randomly in all the directions, inside the metal piece. • If a battery is connected across a metal piece as shown figure, then the free electrons will move in a particular dire...
If voltage and current waveforms are nonsinusoidal (Eq. 1-1), the above equation does not hold because S contains cross terms in the products of the Fourier series that correspond to voltages and currents of different frequencies, whereas P and Q correspond to voltages and currents of the same...
