Product Summary
The Wireless Current Sensor's wide current range enables introductory and advanced explorations of electricity and basic circuits. Designed with user safety in mind, the sensor can be used to measure currents up to 1 A and includes built-in overload protection. Collected data can be wirelessly transmitted to computers, Chromebooks, tablets, and smartphones. When combined with a Wireless Voltage Sensor, students can explore Ohm's Law, series and parallel circuits, and much more.
Since current can only exist in a complete circuit, the Wireless Current Sensor must be part of that circuit to measure current. It is connected in series and has a very low resistance (0.1 Ω). For this reason, we do not recommend connecting it directly across a battery or other voltage source without a resistive load.
Current sensors in chemistry enable students to count electrons involved in driving reactions much like a scale accounts for mass in reactions. Amperage determines how many atoms are involved in a chemical reaction. Since the two are related, current can be used to find out how much reactant is available in solution. Integrating currents keeps track of how much metal might electroplate onto an electrode.

DC Circuits
Students construct a circuit consisting of two resistors in series and then in parallel. They measure the voltage across the resistors, and the current through the resistors. From their measurements they can infer Kirchhoff's...
Ohm's Law
Students measure the current and voltage across a resistor while varying the output voltage, A graph of voltage versus current will reveal Ohm's Law. This version uses the wireless AC/DC module to vary the voltage.
Capacitors and RC Circuits
Students construct a circuit that charges and discharges a large capacitor through a light bulb. They create a model for their observations and test the model with current sensor data. They measure the voltage across a smaller...
DC Circuits
Students use a voltage sensor, a current sensor, and an AC/DC electronics laboratory to construct simple resistor circuits with resistors in series or in parallel, or both (with at most one parallel loop of resistors), to demonstrate...
RC Circuits
Students use a voltage sensor and a current sensor with the AC/DC electronics laboratory to determine how the potential differences across the resistors and capacitor in a simple RC circuit differ when the capacitor is charging,...
