A na ve approach to calculating the equivalent resistance in a network of resistors is to set up a system of linear equations based on Kirchho ’s laws for the network with an outside current passed between the two nodes of interest, and then to solve for the currents through Draw the diagram to show the arrangement. In my previous Phys.SE question, situated here, I asked about finding the equivalent resistance of the following circuit : . 1. Reduce the circuit to a single resistor at terminals a and b. The questions are divided into 18 different Question Groups. What is the total resistance? The resultant resistance for this combination would therefore be: Solution Problem 61. Find the equivalent resistance at terminals a and b. DC Circuits > Resistive Circuits > Equivalent Resistance Keywords: Resistor, Equivalent Resistor Formulas, Algebra; Length: 3:36 Date Added: 2006-08-29 13:31:25 Filename: resistive_equivResistance_ex1 ID: 70 Problem 2 .
Series and parallel resistors on Brilliant, the largest community of math and science problem solvers. This means the resistors must be connected in parallel. So the total resistance would be the resistance of this equivalent resistor added to the resistance of R 6 and R 7. So, to get maximum current, the equivalent resistance has to be less. Example : Find the equivalent resistance between A and B in the circuit shown here. If you're seeing this message, it means we're having trouble loading external resources on our website.
