Krichoff's Voltage Law

Introduction In this experiment we allow for analyze ii truly common circuits configuration: serial resister and check resisters. we will se that serial publication immunitys acts like a potential variety divider, and parallel resistors act like a current divider. Also series and parallel resistors provide undiversified currents. In the betoken 1 below three resistors R1, R2 and R3 be in series. with a potency source on the left. Kirchoffs potential drop Law states that the sum of potentiality around a kink 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 eer 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. directly if we consider a circuit in prognosticate 2 where 3 resistors R1, R2 and R3 are in parallel with a potential drop source. The voltage across each of the resistors will be the same but the currents divides. Considering the single node circuit illustrated in take in 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 exemption of each figure 4A, 4B and 4C are reason. 2. for each one of the res istors in the figure 4A, 4B and 4C are cros! s 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.
