ork: Find the equivalent resistance at terminals a-b for each of the networks in the following Lecture 4-Resistors Analysis circuits. R R. R b. (a) (b) (c)

If you have circuit that contains resistors in parallel, what would be the advantage of finding their equivalent resistance when performing circuit analysis? So that you can easily find the current through the resistors using a single Ohm's Law calculation. So that you can alter the circuit and reduce the number of resistors used. So that you don't have to write a bunch of KCL & KVL equations to find their individual resistances. So that you can apply a current divider expression to find the voltage across each resistor.

How do find the equivalent resistance of multiple resistors configures in parallel? You sum the resistances together and then divide by the number of resistors You average all of the individual resistor values. You calculate: 1/ (1/R1 + 1/R2 + + 1/Rn) ... You use the smallest resistor value.
