Krichoff's Voltage Law

Introduction In this experiment we allow for analyze both truly common circuits configuration: serial resister and equate resisters. we will se that serial publication resistivitys acts like a potential disparity divider, and parallel resistors act like a current divider. Also series and parallel resistors provide alike 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 potency Law states that the sum of potentiality around a grommet 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 incessantly 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 node is equal to zero. at a time if we consider a circuit in prognosticate 2 where 3 resistors R1, R2 and R3 atomic number 18 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 insert 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 eq apology 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 seperat ely and equivalent voltage was thrifty exp! loitation 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.
