A multimeter is an instrument used to measure electrical resistance, voltage, and current. Each students is required to have a digital multimeter for this class. We recommend purchasing a modestly low-cost meter in the range $15 to $35 for this class. A $15 multimeter is perfectly adequate.
Free advice: DO NOT buy a $5 multimeter. Students have had difficulty with those inexpensive meters in the past.
Students will be taught how to use a multimeter to troubleshoot electrical circuits, and to verify important fundamental principles of DC circuits.
A $15, multifunction multimeter is fine. Don't buy the cheap $5 multimeters.
