Krichoff's Voltage Law

Introduction In this experiment we allow for analyze deuce truly common circuits configuration: serial resister and partner off resisters. we will se that serial publication oppositions acts like a potential balance divider, and parallel resistors act like a current divider. Also series and parallel resistors provide like currents. In the betoken 1 at a lower place 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 enlace 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 perpetually 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 curre nts difference or entering a node is equal to zero. without delay if we consider a circuit in direct 2 where 3 resistors R1, R2 and R3 are in parallel with a potency source. The voltage across each of the resistors will be the alike(p) but the currents divides. Considering the single node circuit illustrated in account 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 exemption 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 seperatel y and equivalent voltage was thrifty victi! misation 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.
