Experiment 15 Voltage, Current, and Resistance

Larry Arnold of the National Soil Survey Laboratory assigns unique identification labels to soil samples in preparation to logging the samples and their unique field information into a LIMS. 

Multimeters have sockets into which test leads are inserted. Test leads are insulated wires that have banana plugs on one end, for insertion into the sockets, and metal tips on the other end, for contacting the points in the circuit that are being measured. 

Obtain a socket board and multimeter with test leads from your instructor. If not already done, insert the banana plugs on the one end of the test leads into the sockets on the multimeter for volt and ohm measurement.
