Learners use the CBL and voltage probe to observe electricity. For this algebra lesson, students use the TI calculator with the CBL to explore Ohm's Law. They discuss exponential equations and how it relates to Ohm's Law.

Learners collect and analyze voltage data. Then, they investigate exponential functions using the TI and a Voltage Probe and graph their data and analyze it using a table.

In this activity, students' will use a voltage probe to collect voltage data from a discharging capacitor. They will model potential data using an exponential function.
