Krichoff's Voltage Law

Introduction In this experiment we allow for analyze two truly common circuits configuration: serial resister and equal resisters. we will se that serial publication ohmic resistances acts like a potential digression divider, and parallel resistors act like a current divider. Also series and parallel resistors provide kindred currents. In the betoken 1 below three resistors R1, R2 and R3 atomic number 18 in series. with a potency source on the left. Kirchoffs potentiality Law states that the sum of potentiality around a intertwine 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 argon quintage across resistors R1, R2 and R3. since the current across the series loop is unceasingly 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 the sum of the c urrents difference or entering a node is equal to zero. instantaneously if we consider a circuit in protrude 2 where 3 resistors R1, R2 and R3 atomic number 18 in parallel with a potentiality source. The voltage across each of the resistors will be the akin but the currents divides. Considering the single node circuit illustrated in finger 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 equivalent guard of each figure 4A, 4B and 4C are reason. 2. for each one of the resistors in the f! igure 4A, 4B and 4C are cross out up seperately and equivalent voltage was thrifty utilise ohmmeter. 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.
