Krichoff's Voltage Law

Introduction In this experiment we allow for analyze twain truly common circuits configuration: serial resister and duette resisters. we will se that serial publication resistors acts like a potential departure divider, and parallel resistors act like a current divider. Also series and parallel resistors provide analogous currents. In the betoken 1 downstairs three resistors R1, R2 and R3 atomic number 18 in series. with a potency source on the left. Kirchoffs electromotive force Law states that the sum of potentiality around a circle 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 be quintage across resistors R1, R2 and R3. since the current across the series loop is ever 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 current s difference or entering a node is equal to zero. like a shot if we consider a circuit in work up 2 where 3 resistors R1, R2 and R3 argon in parallel with a potential drop source. The voltage across each of the resistors will be the corresponding but the currents divides. Considering the single node circuit illustrated in flesh 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 identical guard of each figure 4A, 4B and 4C are reason. 2. for eac h one of the resistors in the figure 4A, 4B ! and 4C are cross out up seperately and equivalent voltage was thrifty victimisation 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.
