This lab demonstrates how to use myDAQ to measure resistance R, current I, and voltage V. The relationship between R, I, and V (or Ohm’s Law V = IR) is studied. Also shown are sensors that convert physical measurements like temperature, pressure, and/or strain into a resistance, a current, or a voltage.
Resistors are the most common component found in all electrical and electronic circuits. Resistors are found in many shapes, sizes, and values. The most common shape is a twolead cylinder component with leads coming out each end and color bands painted around the cylinder to indicate the nominal resistor value and its tolerance.
Red and Black DMM Probes (supplied in myDAQ box)
Various Resistors: 47K, 10K, 10K Potentiometer
Solderless Breadboard (recommended)
