Voltage Measurements

Measuring the voltage of a battery using a DMM. A brand new AAA battery would generally have a voltage of 1.5V. From this we can see that this battery is slightly used
Students are introduced to the concept and properties of voltage, including how it relates to current and resistance and how it is measured across various points in a circuit. First students will explore using a DMM to take voltage measurements of everyday objects. Following that, they will explore the relationship between voltage, current, and resistance in a circuit through Ohm's law and Kirchoff's Voltage Law. Finally they will look at several types of voltage measurements including AC/DC measurements as well as Single-Ended and Differential measurements
