Equivalent Resistance - an overview ScienceDirect Topic

Consider finding the equivalent resistance of the network shown below. We see the resistors R 1 and R 2 are connected in series. So their equivalent resistance (let us denote it by R s) is: R s = R 1 + R 2 = 100 Ω + 300 Ω = 400 Ω. Next, we see the resistors R 3 and R 4 are connected in parallel The equivalent resistance is always bigger than any of the individual resistors, R eq > R m. In fact, if one resistor is much much bigger than the rest, the equivalent resistance will be approximately equal to the one big resistor. For example, in the three-resistor string on the previous page, if

Simple equivalent resistance calculations in electric circuits are based on appropriate use of lumped or averaged properties. For instance, the series and parallel equivalent resistor formulas used in freshman physics assume steady, single-directional conditions, e.g., see Fig. 1.1.Similar results are desired in reservoir engineering to increase computing speed, but in several widely used. Equivalent resistance may sound complicated, but it's just a technical way to say the sum of the resistance. In the equivalent resistance of an electrical network, a single resistor can substitute the complete network so that a particular applied voltage or the equivalent current can be obtained similar to the one when utilized as a network Practical capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance.However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance (ESR).If not otherwise specified, the ESR is always an AC resistance.

For resistors in series, the voltage across each resistor does not follow the same rule as the current Previously in Lesson 4, the method for determining the equivalent resistance of parallel are equal, then the total or equivalent resistance of those branches is equal to the resistance of one branch divided by the number of branches. This method is consistent with the formula 1 / R eq = 1 / R 1 + 1 / R 2 + 1 / R 3 +. The equivalent series resistance of a capacitor is the internal resistance that appears in series with the capacitance of the device. Almost all capacitors exhibit this property at varying degrees depending on the construction, dielectric materials, quality, and reliability of the capacitor.
