Krichoff's Voltage Law

Introduction In this experiment we allow for analyze deuce truly common circuits configuration: serial resister and compeer resisters. we will se that serial publication resistors acts like a potential conflict divider, and parallel resistors act like a current divider. Also series and parallel resistors provide kindred currents. In the betoken 1 infra three resistors R1, R2 and R3 be in series. with a potency source on the left. Kirchoffs emf Law states that the sum of potentiality around a eyehole 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 are quintage across resistors R1, R2 and R3. since the current across the series loop is eternally 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 currents difference or entering a n ode is equal to zero. right off if we consider a circuit in move into 2 where 3 resistors R1, R2 and R3 are in parallel with a voltage source. The voltage across each of the resistors will be the same but the currents divides. Considering the single node circuit illustrated in infix 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 akin unsusceptibility of each figure 4A, 4B and 4C are reason. 2. for each one of the resistors in the figure 4A, 4 B and 4C are cross out up seperately and eq! uivalent voltage was thrifty employ 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.
