In this chapter, let us solve an example problem by considering both series and parallel combinations of similar passive elements. Let us find the equivalent resistance ... 4 Ways to Calculate Total Resistance in Circuits wikiHow In a series circuit, the total resistance is equal to the sum of all resistances. The same current passes through each resistor, so each resistor does its job as you would expect. For example, a series circuit has a 2 Ω (ohm) resistor, a 5 Ω resistor, and a 7 Ω resistor. The total resistance of the circuit is 2 5 7 = 14 Ω. Thevenin Theorem: The Thevenin Equivalent Circuit The simplified circuit with a fixed resistor called Thevenin equivalent resistance R­­ th, in series with a variable load resistor, which varies frequently, R­­ ­L, and a Thevenin voltage, V ­th. In other words, any one port electrical network can be reduced to a single voltage source and a single resistor circuit. Norton's Theorem. Step by Step Procedure with Example This is another useful theorem to analyze electric circuits like Thevenin’s Theorem, which reduces linear, active circuits and complex networks into a simple equivalent circuit. The main difference between Thevenin’s theorem and Norton’s theorem is that, Thevenin’s theorem provides an equivalent voltage source and an equivalent series resistance, while Norton’s theorem provides an ... Series Parallel Circuit | Series Parallel Circuit Examples ... The circuit now becomes a simple two resistor series circuit. Fig.2: Series Parallel Circuit and Equivalent Circuit.
