Power Measurement

According to Blondel's theorem, the total power is measured with one less number of wattmeters than the number of wires present in the system. So, a single-phase and two-wire system will require one wattmeter and a single-phase and the three-wire system will require two wattmeters, and a three-phase and the three-wire system will also require two wattmeters and a three-phase and the four-wire system will require three wattmeter devices. The wattmeter is a device that measures power using one voltage and one current input as shown in the above figure. Multiple current or voltage input pair cables are used by many power analyzers and digital storage oscilloscopes (DSOs) for measuring watts, in effect within a single instrument acting as multiple wattmeters. It is possible to measure three-phase and four-wire power with one correctly specified power analyzer.

As with the nodal analysis, the analysis of meshes for an electrical circuit is quite advantageous. This is because it also, to be developed, does not need a high number of equations. In practice, the main objective of this technique is to search for the intensities of called mesh currents. This is what can be done in the circuit presented below. Case the analysis of its meshes is carried out on it, what will be the current intensities found?
Short Problem: Given a parallel RLC circuit comprised of the following element: 97.19-ohm resistor, ideal inductor with reactance of 36.14 ohms; and a capacitor with reactance of 16.25 ohms. Compute for true power in watts given an ac voltage source of 100 cis 0 volts. Note: Follow this reminder carefully. Compute to the nearest 4 decimal places. No Scientific notation. Do not round off in the middle of calculation. Use stored values. Write the numerical values only. No units in your final answer. Spaces are not allowed. Excessive number of decimals as compared to the required number of decimals may result to an incorrect answer.
In some situations it is necessary to replace part of an electrical circuit. However, this must be carried out following certain criteria. The main one states that tension and current intensity, in the sector where the replacement occurred, must remain constant.In this we have what is known as the Substitution Theorem. For example, suppose that the circuit below it is necessary to replace the parts between terminals A and B. This will occur putting in their place a voltage source and a resistor. Calculate voltage and resistance that they must present.
