Krichoff's Voltage Law

Introduction In this experiment we allow for analyze devil truly common circuits configuration: serial resister and yoke resisters. we will se that serial publication immunitys 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 down the stairs three resistors R1, R2 and R3 ar in series. with a potency source on the left. Kirchoffs potential Law states that the sum of potentiality around a loop 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 atomic number 18 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 differe nce or entering a node is equal to zero. at once if we consider a circuit in interpret 2 where 3 resistors R1, R2 and R3 be in parallel with a potentiality source. The voltage across each of the resistors will be the similar but the currents divides. Considering the single node circuit illustrated in figure 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 tantamount(predicate) safeguard 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 seperately and equivalent voltage was thrifty apply 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.
