Voltage and Current Measurement Vocabulary  Electric Circuit  Voltage  Current  Series  Parallel 9

Electric Circuits  A set of electrical components  Sources, Resistors, Inductors, Capacitors 10

Voltage: Volts (V)  Potential Difference between two points  Always has polarity (+/-)  Measure voltage in parallel 11

Current: Amperes (A)  The flow of electrical charge through a conductor or circuit element  Current flow requires a continuous path  Measure current in SERIES 12

Series Circuits    Elements placed one after another V Total = V A I A = I B = I C + V B + V C 13

Parallel Circuits  Multiple elements connected to the same node   I V A = V B = V C Total = I A + I B +I C 14

Resistors     Carbon Wire wound Precision Power Rating

Ohm's Circuit Law  Voltage is equal to current times resistance • V =I*R • I = V/R • R = V/I V I R 17

Breadboards    Power and ground connections along top and bottom Columns are connected Components can just be pushed into place 18

Agilent 3630A DC Power Supply 19

Agilent 3630A Controls • Voltage Adjust– 6V and ±20V • Meter Select Button • Output Terminals 20

Fluke Digital Multimeter  Used to measure voltage, current, and resistance  Leads must be moved to measure current or voltage

Summary  Lab Safety  Voltage/Current  Resistors   Color Code Ohm’s Law  Breadboards  Agilent 3630A DC Power Supply  Fluke Digital Multimeter 22

Assignments  Go to the EE Labs’ website • Read Lab 1 and do the Pre-lab  Read ABCs of DMMs • Found under the Resources link • We’ll have a quiz on this material next week 23
