Krichoff's Voltage Law

Introduction In this experiment we allow for analyze both truly common circuits configuration: serial resister and twain resisters. we will se that serial publication electrical resistances acts like a potential unlikeness divider, and parallel resistors act like a current divider. Also series and parallel resistors provide self-coloured currents. In the betoken 1 down the stairs three resistors R1, R2 and R3 argon in series. with a potency source on the left. Kirchoffs electromotive force Law states that the sum of potentiality around a loop topology is equal to zero. at present bounce the loop in simulacrum one we can enunciate that; - Vs +V1 + V2 + V3 = 0 Where V1, V2 and V3 ar quintage across resistors R1, R2 and R3. since the current across the series loop is constantly the similar current across to each one resistor is Is. Vs = V1+V2 +V3 Vs = Is.R1 + Is.R2 +Is.R3 Req = R1 +R2 +R3 [pic] Kirchoffs current Low Kirchoffs Current Low states t he sum of the currents difference or entering a node is equal to zero. flat if we consider a circuit in framing 2 where 3 resistors R1, R2 and R3 ar in parallel with a potency source. The voltage across each of the resistors will be the identical but the currents divides. Considering the single node circuit illustrated in jut 2.

KCL for Parallel resistors -Is + I1 +I2 + I3 = 0 Is = I1 +I2 + I3 Is = V / R1 + V / R2 + V / R3 or, Is / V = 1 / R1 + 1 / R2 + 1 /R3 or, 1/ R eq = 1 / R1 + 1 / R2 + 1 /R3 [pic] Procedure 1. The alike guard of each figure 4A, 4B and 4C are reason. 2. for each one of the resistors in the figure 4A, 4B and 4C are cross out up seperately and equivalent voltage was thrifty using o! hmmeter. Each measured resistors are recorded in the disconcert 1. 3. In the figure below X represent the 5 volt applied and Y represent the ground. Then current was calculated for each figure and measured using ammeter in table 1. 4. Each resistors in each figure was replaced by equivalent voltage using Decade Box and current was measured using ammeter.
