Tech 60 San Jose State UniversityLab 4Manizheh ZandLab 4 – Series and Parallel with LEDsObjectives:1.Explore the difference between parallel and series circuit using LEDs2.Use a multimeter properly to measure current and voltage3.Verify the result using MultisimMaterials Needed:Resistors:o330Ω (3x)o5.1kΩ (3x)o100kΩ (3x)3 different color LEDsTheory:Ohm’s Law:I=VRSeries Circuit:I (current) in a series circuit is always the same through each resistor:Itotal= I1= I2= I3= …Total Resistance in a series circuit is just the sum of the resistors:Rtotal= R1+ R2+ R3+ …Voltage source is the sum of voltage drops across each resistor:Vsrc= VR1+ VR 2+ VR3+ …Parallel Circuit:Isourceis the sum of the currents through each parallel wire:Isrc= I1+ I2+ I3+ …Total Resistance of a parallel circuit is:
